It contains data for 15 point properties, and 17 temperature and pressure dependent properties. Most of the correlations cover the range from -100 C to 800 C and up to 1000 bar, and some extend even beyond this range. Calculated data points match published data very closely. WASP can be used in two different ways, so that its use is similar to using printed Steam Tables, but of course easier and faster. The first way is when you know the temperature and pressure conditions of the ice, water or steam and you want to find the physical properties. If you are working with wet steam you can also enter the steam quality to get some of the combined properties. The second option allows you to search for the conditions that give rise to a specific value of the enthalpy, entropy or density. This is useful when doing calculations involving compression or throttling. The programme has been carefully designed for speed and ease of use. On-screen prompts appear at every step to guide you. In addition there is context sensitive, on-line Help available at all times. If you are ever unsure of what the programme expects you to do, simply pressing the <F1> key will open a window with detailed instructions and information. You can also view any Help Screen at any time by selecting it from a Help Index. WASP is distributed as Shareware. If this copy is registered to anyone other than yourself, then you are entitled to use it for a few weeks to determine its value to you. If you decide to continue using the programme then you must register your copy with Katmar Software. Further details on Shareware and the registration procedure are given later in this manual. Installation and Startup ======================== Your first step should be to make a copy of your distribution disk. Do not use your distribution disk as a working disk. If your distribution disk is a 5.25 inch floppy, write protect it by putting a tab over the notch in the side of the disk. If it is a 3.5 inch stiffy disk write protect it by sliding the plastic button in the corner to open the hole. Take an unused disk of the same size as your distribution disk, label it as your working disk and make sure it is NOT write protected. If you have identical A and B drives insert the distribution disk in Drive A and the working disk in Water and Steam Properties - Version 1.21 Page 1 Drive B. At the DOS prompt type DISKCOPY A: B: and press <ENTER>. If your A and B drives are not the same (or you do not have a Drive B) type DISKCOPY A: A: and press <ENTER>, and then follow the instructions on the screen to swap disks using the distribution disk as the SOURCE disk and the working disk as the TARGET disk. Installation of WASP entails simply copying all the files to either a diskette or to your hard disk. The distribution disk that you received should contain all of the following files :- GETRESP.EXE Utility for interactive batch files VIEW.COM Text file display utility README Brief details on WASP and its distribution README.BAT A batch file used to display or print README REGISTER.DOC Order form for registering your copy of WASP WASP.EXE The executable file for WASP WASPBOOK.DOC The instruction manual for the WASP package WASPDEFS.DTA Holds the selected units etc WASPHELP.HLP The on-line help instructions FILE_ID.DIZ Description for BBS automation OMBUDSMN.ASP ASP Ombudsman policy statement VENDOR.DOC Info for shareware disk distributors and BBSs If instead of these files your disk contains a file named WASP121.ARC, WASP121.ZIP or some similar name then it means that the disk distributor has compressed the files into an archive file to get more onto the distribution disk. In this case you will need to follow the distributor's instructions on how to extract the files from the archive before you can copy them. If you are installing to your hard disk you should copy the files to a separate sub-directory. To create a new sub-directory on your hard drive follow these steps :- 1) Ensure that you are at the DOS prompt, ie display shows C:> (if your hard drive is drive D display shows D:> , etc) 2) If you want the new sub-directory to be off the root directory, type CD\ and press <ENTER>. If you prefer the new sub-directory to be off some other directory, change to that directory. 3) Type MD WASP and press <ENTER>. 4) Type CD WASP and press <ENTER>. Display should show C:\WASP>. If display does not show this, type PROMPT $P$G and press <ENTER>. If your distribution disk contains all the files listed above, insert it into the A: drive and type COPY A:*.* and press <ENTER>. The programme is then ready to run. If your distribution disk does not contain all the files listed above, but instead contains an archived file, copy that file to the new sub-directory (eg COPY A:WASP121.ZIP). Then follow the distributors instructions to un-archive the files. Once the files have been copied you should type WASP and press <ENTER> to start the programme. The programme starts with an Water and Steam Properties - Version 1.21 Page 2 opening screen and then a screen giving brief details of the shareware distribution system, before getting to the programme proper. The initial screens can be skipped by pressing the <SPACE BAR>. If you are short of space on your hard disk you can delete some of the files. Only two files are absolutely essential for running WASP. These are WASP.EXE and WASPDEFS.DTA. If you want to be able to use the on-line help facility you will also need the file WASPHELP.HLP, but the programme can run without it. When you pass on copies of WASP to others please always include all the files on the distribution disk so that the recipient can make a full evaluation of the package. Hardware and Software Requirements ================================== WASP will run on virtually any IBM(tm) PC or compatible machine. It has been designed to be able to be used on a minimum specification system, but also to make use of higher specification equipment if available. For example it will run perfectly well on a monochrome screen, but will switch to colour if it detects a colour video card. Similarly it will use a numeric co-processor if it finds one, but will run quite happily (although of course more slowly) if none is found. Some EGA and VGA displays, particularly on portable computers, use varying shades of grey rather than true colour. WASP would detect these machines as having colour screens and you may have some difficulty reading the display. In this case you can force the programme to use the monochrome palette by pressing <Alt M> at the opening screen or by using the /M command line switch i.e. start the programme by typing WASP /M. When you exit from the programme it will store this choice and start up in monochrome mode the next time you use it. Summary of system requirements :- DOS : 2.11 or later RAM : 512k or more DISK : 360k or larger floppy, stiffy or hard disk VIDEO : Monochrome, CGA, EGA, VGA or compatible Co-processor : Optional Quick Start for Experienced Users ================================= Even if you are only a moderately experienced computer user you should be able to use WASP without going into this manual in any depth at all. The brief instructions that follow in this section should be all you need to make full use of the programme. The programme will guide you with on-screen prompts at every stage and on-line help is always available by pressing <F1>. Water and Steam Properties - Version 1.21 Page 3 The programme is started by typing WASP, or WASP /M if you want to force monochrome mode on a colour screen. The opening screens can be skipped by pressing the <SPACE BAR> or virtually any other key. After the opening screens you will see the DATA ENTRY screen. This is used when you know the conditions of temperature and pressure, and you want to find the physical properties. In the general case you will enter the temperature and pressure, pressing <ENTER> after each entry. For the specific case of saturated conditions you need to enter either the temperature or the pressure, but not both. In this case you can use <TAB> to ensure that the property you want to enter is on the top line in the box and then key in the value. After typing the value, press <SPACE BAR> instead of <ENTER> and the programme will calculate the corresponding value for saturated conditions. After you have specified the conditions the programme will calculate the properties and display them. There are two forms for the results screens. These are a brief and a full format screen. You can toggle between the two by pressing <F2>. If you are working with saturated liquid and vapour you can set the wet steam quality by pressing <Alt W> at the results screen. If you want to find the conditions that result in a specific value for the enthalpy, entropy or density call the Search function by pressing <Alt S> at the Data Entry or Results screen. Use <TAB> to select the property you want to find. The entry fields in the Search function will default to the last properties calculated and displayed on the Results screen. Under saturated conditions the Results Screen will show values for each phase. The Search function follows a simple rule to select which value will become the default - It always defaults to the vapour value UNLESS it is displaying wet steam properties and then it will take the wet steam value. During data entry the editing keys work in a very standard way, and should not give you any trouble at all. If there is already a value in the entry field you can accept it by pressing <ENTER> or <SPACE BAR>. If you want to enter a completely different value just start typing and the original value will disappear. However if the first key you press is an <ARROW> key the programme will assume you want to edit the displayed value and will not clear it. While either the DATA ENTRY or RESULT screen is displayed you can call up a list of fixed properties with the <F3> key. Pressing <F3> again will take you back to where you were. The units in which you specify the conditions, and in which the properties are displayed, can be changed with the <F4> key. The units can be selected in pre-defined sets, or individually if you want to mix systems of units. Water and Steam Properties - Version 1.21 Page 4 Printing the Manual =================== If you are reading this on your screen and you want to make a hard copy on your printer you can do it in one of two ways. The easiest way is to run the programme and then press <Alt P> at the opening screen. The other way is to type PRINT WASPBOOK.DOC at the DOS prompt. Detailed Operating Instructions =============================== This section gives full details for each step of using the programme. Start-up -------- If you are running WASP from the DOS prompt (eg C:\>) it will be necessary to change to the directory into which you copied the files. You should then type WASP and press <ENTER> to start the programme. If you want to force a colour video card to display in monochrome you can start the programme with the WASP /M command. If you are using a hard disk manager or menu system all this should be automated into the menu. When the programme starts it will display the opening screen with the version and copyright information. After a while it will skip to the shareware distribution notice screen. Both of these screens can be skipped by pressing <SPACE BAR> or <ENTER>. If you have a colour video card but a monochrome screen, as is often the case with portable computers, you may have problems reading the screen. If this is the case, press <Alt M> to switch to the monochrome colour scheme. On-line Help System ------------------- At any stage during the running of the programme you can press <F1> and get help on the specific item on which you are working. Once you are in the Help window you will see in the top right corner the message "Page x of y". If there is more than one page of help available you can page through the help windows by pressing <PgUp>, <PgDn>, <Home> and <End>. The message in the bottom right corner tells you whether you can page up or down. There will also be flashing arrows on the right hand side that show if there is more information above or below the current page. If you press <F1> while a help screen is being displayed you will be shown an index of all the help available for this programme. From this index you can select any one of the help topics that are Water and Steam Properties - Version 1.21 Page 5 available. Simply use the <Arrow> keys to highlight the topic on which you want help, and press <ENTER>. After you have read that help topic you can return to the Help Index by pressing <F1> again. You can switch back and forth like this as often as you like. When you have read all the help you want, you can return to where you left the programme by pressing <Esc>. Data Entry ---------- The Data Entry screen allows you to specify the temperature and pressure at which the physical properties will be calculated. This can be done in several ways, described below. Apart from specifying these conditions there are other options available on the Data Entry screen. Pressing <F3> will display the physical properties that do not vary with temperature or pressure. Pressing <F4> allows you to specify the units in which your entry is made, and in which the properties will be displayed. Although the Search function is not shown in the menu at the bottom of the screen, you can use <Alt S> to jump directly to the screen for entering the Search parameters. If you have a colour video card <Alt C> and <Alt M> will switch between colour and monochrome. If you want to exit WASP press <Alt X>. If you want to calculate the physical properties under SATURATED solid/vapour or liquid/vapour conditions you need to specify either the temperature or pressure, but not both. The entry must be made on the top line and the <TAB> key is used to select which of these you will enter. For example, if the programme is requesting you to enter the temperature on the top line of the input box, but you want to specify the pressure, press <TAB> to swop the two lines. Under saturated conditions it is not necessary to press <ENTER> after you have keyed in the number. Just press the <SPACE BAR> and the corresponding value will be inserted and the properties will be calculated. In order to calculate the physical properties at conditions other than saturated, you have to specify both the temperature and the pressure. You can swop the two entry lines with <TAB>, and you can move the cursor from one line to the other with the up and down arrow keys. When you have keyed in the value on the bottom line pressing <ENTER> will calculate the physical properties. As you enter the conditions the programme will check that they fall in the range covered by the data. If they are not valid entries, the allowable range will be displayed at the bottom of the screen in Water and Steam Properties - Version 1.21 Page 6 the units selected, and you will be asked to re-enter the value. The allowable temperature range is from 166 to 1273 Kelvin (-160 to 1832 Fahrenheit) and the allowable pressure range is from 3.4e-7 to 100 000 kPa absolute (4.9e-8 to 14500 PSI absolute). During data entry the left and right arrow keys, and the <HOME> and <END> keys, allow you to move the cursor back and forth within the entry field. The <DELETE> key deletes the character under the cursor and the <BACKSPACE> key deletes the character to the left of the cursor. <Ctrl BACKSPACE> will delete the entire entry field. If the entry field already contains a number and you press a numeric key before any of the editing keys, the programme will assume that you want to override the original entry and will delete it before displaying the character you have keyed. If you want to accept what is already displayed just press <ENTER> or <SPACE BAR>, depending on whether you are working under saturated conditions or not. Data entry always works in INSERT mode, i.e. characters under and to the right of the cursor will be moved to make space for the new character. Only numeric characters will be accepted, except that <e> can be used to signify exponential notation. E.g. the value 2000 can be entered as 2e3, and 0.001 can be entered as 1e-3. Results Screens --------------- There are several different formats for the results screens that display the physical properties. The format of these screens varies according to the phases that are present, and according to the choices that you have made. However, all screens follow the same basic pattern. The highlighted box at the top of the screen shows the temperature and pressure that you specified and also shows the phases that will be present. The main result box in the centre of the screen gives all the physical properties, the units and the values for each phase. Every alternate line in this box is highlighted to make it easier to follow the line across the screen. The bottom line of the result box shows some of the options available. If you press <Esc>, or in fact any alphanumeric key, you will be returned to the Data Entry screen. The <F2> function key toggles between the full and brief versions of the output screens. The brief results screen gives the properties usually found in "Steam Tables". The full screen gives the same information plus the less frequently needed properties. The brief screen is easier to use because it contains less information. Water and Steam Properties - Version 1.21 Page 7 When you exit from WASP, the programme will make a note of which results screen you had chosen, and will use this choice when it is re-started. When the properties are being shown for saturated liquid and vapour the enthalpy, entropy and density for wet steam can be displayed. These properties are only shown on the brief results screen to avoid cluttering the display. You can use the <F2> toggle described above to switch the results screens. While the results screen is being displayed you can press <Alt W> to set the steam quality. Although the <Alt W> prompt is only shown on the brief screen menu, it is also available from the full results screen. If <Alt W> is pressed from the full screen and a steam quality is entered, the display will automatically switch to the brief results screen. The display of the wet steam properties can be disabled by pressing <F10> when the programme is requesting the steam quality ( i.e. after pressing <Alt W> ). If you want to search for the conditions that give rise to a specific value of enthalpy, entropy or density press <Alt S> to call the Search function. Full details on using the Search function are given in a separate section below. Although it is not shown in the list of options you can use the <F3> function key to display the fixed physical properties. The <F4> key allows you to choose the units in which the properties are displayed. You can select standard sets of units, or choose the units for each property individually. Further information on making these choices is available in the section on Selecting Units below. If you have a colour video card pressing <Alt C> and <Alt M> will switch between colour and monochrome output. You can exit from WASP by pressing <Alt X>. Properties of Wet Steam ----------------------- The enthalpy, entropy and density of wet steam can be shown, if required and applicable. It is of course only available when working with saturated liquid and vapour. It is only shown on the brief results screen. You can switch to this screen by pressing <F2> while the full screen is being displayed. In order to set the steam quality, press <Alt W> at the results screen. This option is only shown on the brief results screen menu, but is available from the full results screen as well. When <Alt W> is pressed from the full screen, the output will automatically switch to brief. The display of wet steam properties can be toggled on and off. The toggle is set on by pressing <Alt W> at the results screen and then entering the steam quality. It is set off by pressing <Alt W> again, and then pressing <F10> when the steam quality is displayed. Water and Steam Properties - Version 1.21 Page 8 The setting of this toggle, and the last steam quality entered (or calculated by the Search function) are retained when you leave WASP, ready for use as defaults in the next session. Note that the steam quality is defined here as the percentage of vapour present, whereas some texts refer to the moisture content. Searching for Specific Values of Properties ------------------------------------------- The Search function is aimed at easily finding the conditions of temperature and pressure that give rise to known values of enthalpy, entropy or density. This function can be called from the Data Entry Screen or from the Results Screens by pressing <Alt S>. After pressing <Alt S> you will be asked to enter the Search Parameters. On the first line you must enter the value for any one of enthalpy, entropy or density. Before you enter the value you can select the property you want to search for by pressing <TAB>. Once you have selected the property, WASP will keep prompting for that one each time you use the Search function until you change it by pressing <TAB> again. If you have already used WASP to calculate the physical properties at some conditions, you will see that the entry on the first line has defaulted to the calculated value shown on the last Results Screen. You can accept this value by pressing <ENTER>, or you can simply type in the new value. Entering a value in this field works in the same way as on the Data Entry Screen. Under saturated conditions the Results Screen will show values for each phase. The Search function follows a simple rule to select which value will become the default - It always defaults to the vapour value UNLESS it is displaying wet steam properties and then it will take the wet steam value. If you want to force the Search function to take the saturated vapour value as the default you must either disable the display of the wet steam properties or enter a steam quality of 100 %. Setting the steam quality to 0 % will effectively make the saturated liquid value the default. On the second line you must enter either the temperature or the pressure, and the programme will search for the other. Here again you select the property you want to enter by pressing <TAB>. The default values will be the last ones you entered on the Data Entry Screen. While making these entries you can change the units used by pressing <F4>. After you have entered the Search Parameters the programme will try to find either the temperature or pressure that will satisfy them. If the search is successful it will then display the value it finds, Water and Steam Properties - Version 1.21 Page 9 together with the fluid condition. At this stage you can press <ENTER> to see all the properties shown on the Results Screen, or press <Esc> to re-enter the Search Parameters. If no value can be found to satisfy the Search Parameters WASP will advise you of the fact and then you can press <Esc> to re-enter the Search Parameters, or press <F10> to abandon the Search function. The programme limitations that could cause the search to be unsuccessful are described below. The range over which WASP can search for values of the chosen properties is basically the same as that where it can calculate those properties, with two exceptions. The first is that it will not search in the solid phase. The second area that may cause problems is searching for the pressure that gives a known enthalpy in the liquid phase. At some temperatures the enthalpy of the liquid first decreases as the pressure increases, and then increases at higher pressures. The linear search technique used by WASP fails under these conditions. In real life this will rarely cause problems. A word of caution is necessary when using the Search function. In some areas the physical properties change very slowly, particularly with changes in pressure. A good example is the entropy of liquid water. If you take a value from a set of Steam Tables, and then use WASP to search for it, you may find that it reports a pressure significantly different from the Steam Tables. So although WASP will very accurately calculate the properties when given the conditions, the reverse is not always true. This will be less of a problem when working with changes in a property and WASP is used to calculate the properties before and after the change. As always, for a critical design, cross check with other data sources. Calculation Examples -------------------- The following examples are given so that you can work through them on your computer and get the "feel" of the WASP Search function. All of these examples are given in SI and Customary Units. Please press <F4> and select one of these two sets of units before tackling an example problem. In all of the examples we will use the Data Entry screen to enter the initial conditions and to calculate the properties under those conditions. One of these properties will then be used to search for the final conditions. In order to decrease the typing required WASP uses the last calculated properties as the default entries for the Search function. Under saturated conditions the Results Screen will show values for each phase. The Search function follows a simple rule to select which value will become the default - It always defaults to the Water and Steam Properties - Version 1.21 Page 10 vapour value UNLESS it is displaying wet steam properties and then it will take the wet steam value. Example 1 - Constant Volume Process ------------------------------------- Wet steam is heated at constant volume from the initial conditions shown below to a temperature of 900 Fahrenheit ( 755.37 Kelvin ). Determine the initial temperature, and the final condition and pressure. Initial Conditions :- Quality 90 % Pressure 300 PSI abs 2068.4 kPa abs Procedure :- At the Data Entry screen press <F4> to set the units to either SI or Customary Units, according to your preference. While still at the Data Entry screen press <TAB> to ensure that Pressure is on the top line in the box. Key in the pressure, i.e. 300 PSI abs or 2068.4 kPa abs. As we are dealing with wet saturated steam press <SPACE BAR> to generate the saturation temperature. The Results Screen shows that the initial temperature is 417.3 Fahrenheit or 487.2 Kelvin. Press <Alt W> to enter the steam quality, key in 90.0 and press <Enter>. Because the volume and mass are constant the steam density (or specific volume) will remain constant. We can therefore use the WASP Search function to locate the conditions that give this known density ( i.e. 0.7187 lb/ft3 or 11.513 kg/m3 ). Press <Alt S> to call up the Search function. Press <TAB> to ensure that Density / Volume is on the top line in the box. Note that the correct density already appears in the entry field, because when using the Search function WASP will default to the last value calculated for wet steam. Press <Enter> to accept this density. As we know the final temperature, press <TAB> to ensure that Temperature is on the bottom line of the box. Key in 900 Fahrenheit or 755.37 Kelvin and press <Enter>. The Search Results screen will echo the density and temperature entry values, and also shows us that the steam is now in the Superheated Vapour condition and that the pressure is 562.4 PSI abs or 3877.7 kPa abs. If you press <Enter> again you will see all the properties under the new conditions. Water and Steam Properties - Version 1.21 Page 11 Example 2 - Constant Entropy Process -------------------------------------- Steam expands under constant entropy conditions from the initial conditions shown below to a pressure of 25 PSI abs (172.37 kPa abs). Determine the initial condition, and the final condition and temperature. Initial Conditions :- Pressure 1800 PSI abs 12410.4 kPa abs Temperature 900 Fahrenheit 755.37 Kelvin Procedure :- At the Data Entry screen press <F4> to set the units to either SI or Customary Units, according to your preference. While still at the Data Entry screen, key in the pressure and temperature as given above. The Results Screen shows that the initial condition is Superheated Vapour, and that the entropy is 1.5277 Btu/lb.F or 6.9350 kJ/kg.K. We can use the WASP Search function to locate the conditions that give this entropy. Press <Alt S> to call up the Search function. Press <TAB> to ensure that Entropy is on the top line in the box. Note that the correct entropy already appears in the entry field, because when using the Search function WASP will default to the last value calculated. Press <Enter> to accept this entropy. As we know the final pressure, press <TAB> to ensure that Pressure is on the bottom line of the box. Key in 25 PSI abs or 172.37 kPa abs and press <Enter>. The Search Results screen will echo the entropy and pressure entry values, and also shows us that the steam is now in the Saturated Liquid and Vapour condition with a quality of 86.3 %, and that the temperature is 240.08 Fahrenheit or 388.75 Kelvin. If you press <Enter> again you will see all the properties under the new conditions. Example 3 - Constant Enthalpy Process --------------------------------------- Condensate flows under saturated conditions from a heat exchanger to a flash vessel. The heat exchanger operates at 200 PSI abs (1378.9 kPa abs) and the flash vessel is controlled at 30 PSI abs (206.84 kPa abs). Determine the amount of flash steam generated, and the final temperature of the steam. Initial Conditions :- Quality 0.0 % Pressure 200 PSI abs 1378.9 kPa abs Water and Steam Properties - Version 1.21 Page 12 Procedure :- At the Data Entry screen press <F4> to set the units to either SI or Customary Units, according to your preference. While still at the Data Entry screen press <TAB> to ensure that Pressure is on the top line in the box. Key in the pressure, i.e. 200 PSI abs or 1378.9 kPa abs. As we are dealing with saturated condensate press <SPACE BAR> to generate the saturation temperature. The Results Screen shows that the initial temperature is 381.79 Fahrenheit or 467.47 Kelvin. Press <Alt W> to enter the steam quality, key in 0.0 and press <Enter>. In a throttling process the enthalpy remains constant, so we can therefore use the WASP Search function to locate the conditions that give this known enthalpy ( i.e. 355.46 Btu/lb or 826.44 kJ/kg ). Press <Alt S> to call up the Search function. Press <TAB> to ensure that Enthalpy is on the top line in the box. Note that the correct enthalpy already appears in the entry field, because when using the Search function WASP will default to the last value calculated for wet steam. Press <Enter> to accept this enthalpy. As we know the final pressure, press <TAB> to ensure that Pressure is on the bottom line of the box. Key in 30 PSI abs or 206.84 kPa abs and press <Enter>. The Search Results screen will echo the enthalpy and pressure entry values, and also shows us that the steam is now in the Saturated Liquid and Vapour condition and that the temperature is 250.3 Fahrenheit or 394.5 Kelvin. The quality of the steam is 14.4 %, which means that 14.4% (by mass) of the condensate flowing into the flash vessel will convert to steam. If you press <Enter> again you will see all the properties under the new conditions. Fixed Properties ---------------- The physical properties of water that do not vary with temperature or pressure can be displayed by pressing <F3> at the Data Entry Screen or at the Results Screen displaying the variable properties. The main result box in the centre of the screen gives all the physical properties, the units used and the values for each physical property. Every alternate line in this box is highlighted to make it easier to follow the line across the screen. The bottom line of the result box shows some of the options available. If you press <Esc> or <F3> you will be returned to the screen from where you requested the fixed properties. Water and Steam Properties - Version 1.21 Page 13 The <F4> key allows you to choose the units in which the properties are displayed. You can select standard sets of units, or choose the units for each property individually. Further Help on making these choices is available in the section on Selecting Units below. If you have a colour video card pressing <Alt C> and <Alt M> will switch between colour and monochrome output. You can exit from WASP by pressing <Alt X>. Selecting Units --------------- The units that are used for data entry and for displaying the physical properties can be chosen in sets, or individually for each property. The <F4> key can be pressed at any data entry or results screen to call up the menu for selecting the units. The first 5 options on the menu select the sets of units and the balance of the options are for the individual units. There are two ways to make a selection from the menu. The first is the "Point-and-Shoot" method. Use the arrow keys to highlight your choice, and then press <ENTER>. The second method is faster, requiring only a single key press. Simply press the alphabetic key corresponding to your choice. You can see which units are currently selected by pressing <SPACE BAR> while the menu is displayed. If you select one of the sets of units, the programme will display the units that will be used for each property. Press <Esc> to get back to the menu, and again to get back to the point from where you called the Units menu. When you choose to change the units for an individual property you will be shown a sub-menu with the available units. In the sub-menu the currently selected unit will be highlighted. The method for selecting the option from the sub-menu is exactly the same as for the main menu. After you make your selection the programme will automatically return to the main menu, from where you can choose to change the units for another property, or you can press <Esc> to quit the menu. The only individual unit that needs further explanation is option "H", ie Density / Specific Volume. Strictly speaking density and specific volume are not the same property, but in WASP they are dealt with together as the one is just the reciprocal of the other. Whenever you exit from WASP, the programme will check to see if the selected units have changed. If they have, it will give you the option of saving the new selection of units for use in the next session. You can revert to the last saved selection of units at any stage during a session by selecting the first option on the units menu. Water and Steam Properties - Version 1.21 Page 14 Using the Menus --------------- All the menus in WASP follow exactly the same format. There are three ways to make a selection from a menu. The first is the "Point-and-Shoot" method. Use the arrow keys to highlight your choice, and then press <ENTER>. The second method is basically the same as the first, except that the mouse is used to highlight the choice. The left mouse button functions as an <ENTER> key and the right button as an <Esc> key. The third method is the fastest, requiring only a single key press. Simply press the alphanumeric key corresponding to your choice. Exiting from WASP ----------------- When you want to exit from WASP press <Alt X>. As the programme quits it will check to see if the selection of units to be used has been changed from what it was at the start of the session. If the selection was changed, the programme will request you to choose whether you want it to start up the next session with the new units, or with the same selection as the current session did. The programme will also save your current selection of full or brief results screen output, whether you were using the colour or monochrome display, the last steam quality used or found and the properties selected in the Search function. These selections are saved automatically and you will not be prompted to confirm that you want them saved. Accuracy Considerations ======================= The accuracies listed below are given in good faith and reflect our testing of the WASP correlations against a wide range of sources. We believe that the accuracies attained are well within the bounds normally required for process engineering design work, but if you are doing very exacting calculations (particularly if they are near the critical point) you should cross check your data. This cross checking of data is good engineering practice for important design work and its necessity was brought home to us in no uncertain way during the testing of WASP. We found several typographical errors in well known data sources and some of the data tables were just plain wrong. There are probably quite a few installations around the world that were designed using this data ! The accuracies listed are based on comparing the calculated value of the property with the original data source for given values of temperature and pressure. In some areas the physical properties change very slowly, particularly with changes in pressure. A good Water and Steam Properties - Version 1.21 Page 15 example is the entropy of liquid water. If you take a value from a set of Steam Tables, and then use WASP to search for it, you may find that it reports a pressure significantly different from the Steam Tables. So although WASP will very accurately calculate the properties when given the conditions, the reverse is not always true. This will be less of a problem when working with changes in a property and WASP is used to calculate the properties before and after the change. As always, for a critical design, cross check with other data sources. There are accuracy advantages in using a package like WASP in that you will avoid the typo's in the published tables, you will get better interpolations between the published data points and you will not be exposed to the risk of arithmetical errors in converting to different units. The "worst" errors are the worst that we found, and in general were near the critical point.

This section gives details on the shareware system and how it works. The Shareware distribution system can be seen as having developed naturally in the environment of free enterprise and innovation that characterised the PC industry in the early 1980's. It has continued to grow and today there is a huge variety of high quality software available at reasonable prices. Shareware in fact covers a wider range of subjects than commercial software. Some of the areas that are particularly well represented are databases, word processors, spreadsheets, CAD, games, DOS utilities, menuing systems, education, accounting and programming support. A support industry that includes magazines, disk distributors and bulletin board systems has grown up around the Shareware system. If you are new to Shareware you may like to have a look at some of the software available from the disk distributors. They supply evaluation copies of Shareware packages for about US$ 5.00 per disk. This payment is for copying the software and the price of the disk, and *NOT* for the software itself. If you like the software, and decide to continue using it, you send your payment to the author and not to the distributor. Some distributors with good catalogues are :- 1 Public Brand Software, Box 51315, Indianapolis, IN 46241, USA. 2 The Public Domain and Shareware Library, Winscombe House, Beacon Rd, Crowborough, Sussex, TN6 1UL, England. 3 JSE, 73 Highway, Fish Hoek, 7975, South Africa. 4 Seltec New Zealand, PO Box 943, Nelson, New Zealand. 5 Spearwood Shareware Service, PO Box 121, Hamilton Hill, WA 6163, Australia. Water and Steam Properties - Version 1.21 Page 18 The basic concept of Shareware is that the author retains the copyright and all other commercial rights to the software and documentation, while allowing, and indeed encouraging, wide copying and distribution of the package. There are a few restrictions that authors place on distribution. All copies must be full copies of the entire package with no modifications. Copies may not be sold for more than the cost of the disk, the labour of copying and a reasonable profit. When selling copies the distributor must state that the software is free for evaluation purposes only and payment must be made to the author if continued use is made of the programme. Effectively the Shareware author is relying on the users of his software to do part of his marketing by passing on copies. For this reason Shareware is often also called User Supported Software. This system eliminates almost all the advertising and marketing costs that make up the major portion of the operating budgets of commercial software distributors. There are many advantages in Shareware to users and authors. The cost to the user is low because no money is wasted on advertising and fancy packaging that add no real value to the software. The biggest advantage to the user is that it is a true "try-before-you-buy" system. The software can be fully evaluated on the user's hardware and in his own environment before payment is made. Shareware therefore has the ultimate money-back guarantee -- if you don't use the product, you don't pay for it. Another advantage to the user is that by its very nature Shareware cannot be copy protected. This eliminates the hassle of key disks, dongles, immovable sectors on hard disks, special install and uninstall routines and all the other wonderful schemes that have been devised to try the user's patience. As there is no middleman (middlemen ?) not only is the cost kept lower, but the user is also closer to the author and is able to write directly to him for help and advice. Shareware authors generally encourage users to send in "wish-lists" of desired features, and are quite responsive to those requests. There are of course also advantages to the authors who use Shareware to distribute their products. The cost of launching a new product via Shareware is much less than via normal commercial channels. This has allowed smaller software houses to market innovative and highly specialised software that would otherwise simply not be profitable. Running costs are also lower as there are almost no marketing or advertising costs. The software industry is currently going through a consolidation phase with the big-guns buying each other, and some of the smaller guns, out. But a significant number of the small companies have switched to Shareware and have made some really top class software available via this route. Water and Steam Properties - Version 1.21 Page 19 Getting an Up-to-date Evaluation Copy ===================================== If your evaluation copy of WASP is more than a few months old and you want to get the latest copy for evaluation there are three routes you can follow to check what is available. The first is to contact any ASP affiliated disk vendor or BBS. All major upgrades are distributed via the ASP CD to all vendor and BBS members. They should always have a fairly new version. The second is CompuServe. The latest version is always uploaded to the PC Applications Forum. Using your usual CompuServe communications software GO PCAPP and then search LIB 13 "Tech/Eng/Sci" for WASP.ZIP. In an effort to make it easier for you to obtain your favourite software, the latest updates of WASP and many other ASP authored programs can be found on the BBSs listed below. These BBSs are members of the ASP Hub Network (AHN). Zone 1 - East Coast USA North-East Coast Mid-East Coast [Site #1] [Site #2] The Consultant BBS The Break RBBS <East> Jay Caplan Bruce Jackson P.O.

In the case of a dispute contact the ASP Ombudsman. WASP Licensing Policy ===================== This section describes the WASP licensing policy. The WASP licence agreement is basically the usual Shareware policy. Recipients of copies of the WASP package are requested to use the system for a few weeks to determine its value. You only need to pay for it if you believe that it offers the value of the asking price. If it does not meet your needs or standards then it costs you nothing. WASP can be bought either as a single-user system for US$ 40.00 or as a multi-user site licence for US$ 75.00 (or the equivalents in SA Rands). The single-user licence entitles you to install the package onto several different computers on a single site, provided that it is not run on more than one machine at a time. If it is likely that it will be run simultaneously on two or more machines we request that you purchase a site licence. When you register your copy of WASP you will :- o receive the latest version with your company's name listed as the licence holder on the title screen. The registered version will not have the "Test Drive" screen. o receive 12 months of mail or e-mail support. o receive a registration certificate allowing you to to purchase the two disk set CD-ROM JCSM Shareware Collection containing over 4,500 programmes for only $9.95 plus S & H. o be notified of updates to WASP and of new product releases from Katmar Software. o have your suggestions for improvements to WASP added to our "wish list". Water and Steam Properties - Version 1.21 Page 21 o enjoy the satisfaction of knowing you have done the right thing ! Whether you register or not, may we request that you give away copies of WASP to your friends, colleagues, customers, suppliers, students and anyone else who would have a use for it. We would also appreciate it if copies are uploaded to BBSs. The only restriction on distribution is that we ask that you always give away copies of the full system with all its files, and that they are not modified in any way. The full list of files is given in the section on Installation and Startup at the beginning of this manual. Suppliers of hardware and software may bundle WASP with any of their other products, subject to the above restriction, and that it is clearly stated that any payment made is solely for the other product and not for WASP. Software Support Policy ----------------------- If registered users have problems that they cannot solve by reading the on-line help or the manual, they are entitled to support via mail for a period of 12 months from the date of registration. When describing the problem please be as detailed as possible. Screen dumps may be useful in this regard (press <PRINT SCREEN> while the screen in question is being displayed). If you have operational problems include details of your hardware, operating system, resident programmes and so on. Write to us at Katmar Software PO Box 654 Westville 3630 South Africa. If you have a CompuServe address please include it and we will reply by e-mail if it is feasible. Registered users can also contact us on CIS 100100,2050. It is ASP policy that if an unresolvable problem occurs within 3 months of purchase the customer is entitled to a refund of the registration cost. Registration Procedures ----------------------- There are three different ways in which you can pay for your WASP registration. The first method is to place your order with PsL using your credit card. This can be done by telephone, fax or mail. The second is specifically for members of CompuServe. If you use this method, the cost of registration will be added to your Water and Steam Properties - Version 1.21 Page 22 CompuServe bill. The third method allows you to pay by mailing a cheque or money order directly to us. Your registered copy of the software will be sent to you from Katmar Software, whichever method you use. Payment by Credit Card The PsL addresses given below are for orders only. Any other correspondence must be sent to the address given in the section on the Software Support Policy above. You can order with MC, Visa, AmEx, or Discover from Public (software) Library by calling 800-2424-PsL from within the USA or 713-524-6394 from other countries, or by FAX to 713-524-6398 or by CIS E-mail to 71355,470. PsL's office hours for telephonic orders are 7:00am to 6:00pm (ie 18h00) CST Monday to Thursday and 7:00am to 12:30pm (ie 12h30) CST on Fridays. You can also mail credit card orders to PsL at PO Box 35705, Houston, TX 77235-5705. An order form that you can use for FAX or mail purposes is included in the Appendix, or you can print one out by running the programme and pressing <Alt R> at the Shareware Distribution screen. The product code for WASP is #11376. THE ABOVE NUMBERS ARE FOR ORDERS ONLY ------------------------------------- Any questions on the status of the shipment of the order, refunds, registration options, product details, technical support etc must be directed to Katmar Software, PO Box 654, Westville 3630, South Africa. To insure that you get the latest version, PsL will notify us by E-mail the day of your order and we will ship the product directly to you. Payment via CompuServe If you have a CompuServe ID this is the easiest way to register. Log onto CompuServe in the normal way and then GO SWREG. Select "Register Shareware" from the menu. After some legalese a list of search criteria will be displayed. Select option 1 to search by Registration ID. Enter the WASP registration ID, which is 3263 for a single user licence (US$ 40.00) or 3264 for a multi-user site licence (US$ 75.00). CompuServe will display some details on WASP and then ask you to confirm that you want to register. Press "Y" to start the registration process. You will be asked to give the following information :- Water and Steam Properties - Version 1.21 Page 23 Your full name Your company name Your complete address Your telephone number Number of copies to register. Select VIEW to check that the information you entered is correct, and then SEND to complete your registration. CompuServe will advise us of your registration via E-mail, and we will send your registered version immediately. Payment by Cheque or Money Order If you do not have a credit card, or access to CompuServe, you can pay by cheque or money order. The order form that must accompany your cheque can be produced in one of two ways. The easiest way is by running WASP and then pressing <Alt R> at the Shareware Distribution screen and answering the questions. This will print the completed form on your printer. This also has the advantage that we will not have to decipher your hand writing and will be able to address your package accurately! The order form is also contained in the file REGISTER.DOC on the distribution disk. This file can be printed out and filled in manually, or loaded into your word processor for completion and printing. A copy of REGISTER.DOC is attached to the end of this manual. Send your order form plus cheque or money order to :- Katmar Software PO Box 654 Westville 3630 South Africa Registration to Engineering Schools ----------------------------------- Any University or Technical College involved in the tertiary education of engineers can obtain a licence for WASP free of charge. In order to get your registered copy of the latest version please fill in the registration questionnaire in the normal way and get your Head of Department to write a covering letter on your School's official letterhead, but send NO MONEY. All that we ask in return is that you make the registered copy available to all students and staff so that we do not get duplicate requests, and hopefully the students will take their copies with them when they go out into industry. University registrations must be sent directly to Katmar Software in Water and Steam Properties - Version 1.21 Page 24 South Africa. Please do not register via PsL or CompuServe, as you would then be billed for your registration. ASP's Ombudsman Policy ====================== This program is produced by a member of the Association of Shareware Professionals (ASP). ASP wants to make sure that the shareware principle works for you. If you are unable to resolve a shareware- related problem with an ASP member by contacting the member directly, ASP may be able to help. The ASP Ombudsman can help you resolve a dispute or problem with an ASP member, but does not provide technical support for members' products. Please write to the ASP Ombudsman at 545 Grover Road, Muskegon, MI 49442-9427 USA, FAX 616-788-2765 or send a CompuServe message via CompuServe Mail to ASP Ombudsman 70007,3536. Bug Reports and Wish Lists ========================== We have put many hours into the checking of this programme and were not aware of any bugs at the time of release. However, we are also aware that the most subtle bugs are unearthed after release. We are therefore most grateful to those who report bugs to us. Please give as much detail as possible on the bug so that we can re-create the circumstances on our equipment. Please include details of your hardware, operating system, resident programmes and so on. Our experience gained over many years and with the development of several packages has shown us that no matter how much effort we put into designing and planning we can never hope to match the combined creativity of our users. We would like to hear of any features you would like to see changed or added to WASP. Are there units that you use that we have not built in ? Let us know and if they are anything more reasonable than bathtubs/fortnight we will build them in. Are there standard calculations that you would like built in ? If so please send details and samples. Would you like to be able to use WASP on operating systems other than DOS ? Are there any operations in WASP that are awkward and not intuitive or standard ? Let us know how you would prefer it to be. Revision History ================ Jul 93 Version 1.00. First release to selected sites for final testing. Nov 93 Version 1.01. Initial public release of WASP. Jan 94 Version 1.02. Minor cosmetic improvements, particularly to documentation. Thanks to PDSL(UK) and others for helpful suggestions in this regard. Water and Steam Properties - Version 1.21 Page 25 Apr 94 Version 1.1. Documentation and on-line help changed to meet ASP requirements. Aug 94 Version 1.2. Fixed fatal error in low temperature liquid isothermal compressibility calculation. Added wet steam properties. Added search functions for enthalpy, entropy and density. Apr 95 Version 1.21. Fixed bug when changing to new set of units from bottom line of Data Entry screen. Updates and fixes in documentation. Other Engineering Packages from Katmar Software =============================================== Our aim at Katmar Software is to provide top quality process engineering utility software at realistic prices. WASP is the first of our packages to be released. Other applications that we have in various stages of development between conceptual design and beta testing are more physical property database and estimation packages; flow calculations in pipes, valves and orifices; process equipment design and evaluation programmes and so on. As soon as these packages are released as shareware we will advise all registered users of WASP. If there are particular application areas where you have a need for low cost utilities please let us know as we would like to focus our limited resources where they will be most effective. Appendix ======== WASP Registration Form ---------------------- The following registration form is provided for those who would like to fill in their order form manually. You can also complete the registration form by loading the file REGISTER.DOC into your word processor and filling in the missing information before printing it out. Probably the easiest way to register is to run the WASP programme and press <Alt R> at the Shareware Distribution Screen. The programme will ask you the questions and you can type your information directly into the programme. It will then print out the registration form on your printer.
