DEFINITION OF SHAREWARE
Shareware distribution gives users a chance to try software
before buying it. If you try a Shareware program and continue
using it after a reasonable evaluation period, you are expected
to register. Individual programs differ on details -- some
request registration while others require it, some specify a
maximum trial period. With registration, you get anything from
the simple right to continue using the software to an updated
program with printed manual.
Copyright laws apply to both Shareware and commercial software,
and the copyright holder retains all rights, with a few specific
exceptions as stated below. Shareware authors are accomplished
programmers, just like commercial authors, and the programs are
of comparable quality. (In both cases, there are good programs
and bad ones!) The main difference is in the method of
distribution. The author specifically grants the right to copy
and distribute the software, either to all and sundry or to a
specific group. For example, some authors require written
permission before a commercial disk vendor may copy their
Shareware.
Shareware is a distribution method, not a type of software. You
should find software that suits your needs and pocketbook,
whether it's commercial or Shareware. The Shareware system makes
fitting your needs easier, because you can try before you buy.
And because the overhead is low, prices are low also. Shareware
has the ultimate money-back guarantee -- if you don't use the
product, you don't pay for it.

N P S Users' Guide (version 2.0w)

INTRODUCTION
How big is a six inch pipe? If you guessed six inches, you would
be wrong. For many engineers, engineering students, plumbers,
and other professionals, this is a tough question, but one which
needs and answer (usually immediately or sooner!). Finding the
answer used to be a job in itself - searching through the
handbook tables only to discover that the material or size of
pipe you wanted was not listed in the table. Now there is N P S
for Windows, the user friendly computerized database of piping
information from Herne Data Systems Ltd. Written by a
professional engineer, N P S contains data on more than 3000
sizes and types of standard and specialty piping and tubing in
over 25 different materials including metals, plastics and
composites. (N P S is also available in a DOS version. Look for
the file PIPE2x.EXE or PIPE2x.ZIP on your favourite BBS or
shareware supplier).
By the way, the correct answer to the above question is - it
depends on the material and classification of the pipe.
N P S (Nominal Pipe Size) gives the user instant access to all
important piping parameters: true inside and outside diameters,
wall thickness, linear weight, cross sectional and surface areas,
moment of inertia, section modulus, radius of gyration and water
flow capacity in US, Imperial or metric units. The data have
been compiled from a number of international and industrial
standards.
The N P S for Windows program consists of a number of files as
listed below:
NPSW.EXE The main N P S program.
NPS.DTA The piping data file for the N P S program.
NPS.INI (Optional) contains the program default
information. If this file is not present, N P S
will use its own internal defaults of US units for
weights and dimensions, and the first material in
the NPS.DTA piping materials list.
NPSW.DOC This documentation file.
CATALOG.DOC Information on other shareware and commercial
software products available from Herne Data
Systems Ltd.
1
N P S Users' Guide (version 2.0w)
----------------------------------------------------------------
UPDATE.DOC (Optional) contains information on new features or
enhancements since the last version.
PIPEW2.EXE A self extracting PKZIP file containing all of the
above files. You are encouraged to upload this
file to your favourite BBS.
Of the files listed above, only NPSW.EXE and NPS.DTA are
absolutely required to run N P S. NPS.INI is created when you
save new program defaults.
* * * *
This documentation assumes that the reader is reasonably
familiar with the operation of his/her computer and
understands how to invoke simple MS-DOS and Windows
commands.
* * * *
N P S is part of the Engineering Applications and Reference
Series from Herne Data Systems Ltd. This series is designed to
give engineers, scientists and engineering students access to low
cost utilities catering to their technical specialty.
SYSTEM REQUIREMENTS
N P S works on all MS-DOS compatible computers running Microsoft
Windows 3.0 or later. N P S works in all Windows operating
modes: real, standard or 386 enhanced. N P S will run on any
Windows supported network. Any Windows supported display adaptor
and pointing device can be used. A pointing device is not
required, but is recommended for ease of use. A fast hard drive
and plenty of RAM is not required but is recommended for speedy
operation of Windows 3.x.
PRINTING THE DOCUMENTATION
This documentation is in ASCII text format, with no embedded
control codes except for carriage returns, line feeds and page
feeds. It can be printed on any standard dot matrix or laser
(non-PostScript) printer with the DOS COPY command:
COPY NPSW.DOC LPT1:
The text is formatted to print on either 8-1/2 x 11 inch letter
sized paper or metric A4 sized paper. You can also import the
2
N P S Users' Guide (version 2.0w)
----------------------------------------------------------------
text directly into most word processing programs for viewing or
printing. (Consult your word processing program users' guide for
details).
MAKING A BACKUP
Before using N P S for the first time, it is a good idea to make
a backup copy. On a two floppy drive system, this can be done
with a simple DOS COPY *.* command. On a hard drive system, you
may want to create a new subdirectory for N P S (with the command
MD NPSW) before copying the files.
When it is run, N P S will automatically load its data files from
the same subdirectory that the NPSW.EXE file is in. Therefore,
as a minimum the files NPSW.EXE and NPS.DTA must be in the same
subdirectory. If NPS.INI is present, it must be located in the
same subdirectory also.
INSTALLING N P S UNDER WINDOWS 3.x
N P S is designed to run under Microsoft Windows (tm) version 3.0
or later, in any operating mode supported by your system (real,
standard or 386 enhanced). Installing N P S is a simple two step
manual process. Although it is not as flashy as some automatic
installation programs, the manual installation gives you complete
control over where N P S is installed and where it appears on
your Windows desktop. N P S will NOT modify the AUTOEXEC.BAT,
CONFIG.SYS, WIN.INI or SYSTEM.INI files, nor does it require you
to make any modifications.
N P S is installed directly from the Windows Program Manager, or
similar Windows desktop. (For installation using other Windows
desktops, such as Norton Desktop for Windows, consult your users'
guide.) After copying the N P S files to the appropriate sub-
directory on your hard drive,
1) Activate the window for the program group where you wish to
include N P S or create a new group for N P S from the
Program Manager with:
File
New
Program Group
OK
This will open the 'Program Group Properties' dialog box
requesting the details of the new program group: description
and group file. Type 'NPSW' in both edit boxes, then click
3
N P S Users' Guide (version 2.0w)
----------------------------------------------------------------
on OK.
2) Once the program group has been selected or created, click
the mouse on the following Program Manager sequence:
File
New
Program Item
OK
This will open 'Program Item Properties' dialog box
requesting the details of the program: description and
command line. Type 'NPSW v2.0' for the description and the
full path name for the command line (e.g. if you had the
NPSW.EXE program file in the subdirectory \NPSW on C: drive,
the full path would be C:\NPSW\NPSW). Then click on OK. If
the 'run minimized' option is checked, NPSW will load as an
icon when selected. For Windows 3.1, it is not necessary to
enter anything in the 'Working Directory' box.
The N P S icon should appear in the selected program group.
If it does not appear, or an error message is displayed,
check that you have specified the correct path and file name
in the Program Item Properties dialog box.
Installation is now complete.
RUNNING N P S
To run N P S, double click on the N P S icon from the program
manager. If the 'run minimized' option was checked during the
installation, N P S will initialize itself, then be minimized
into an icon. Normally, N P S will expand to fill the entire
screen after initialization. (Admittedly, N P S is a screen hog.
This is necessary to make sure all data can be displayed.)
The main window of N P S is a standard Windows program window
with a caption bar (including system menu box and minimize box),
menu bar and client area. The caption bar will display the name
of the currently selected material. The menu has 5 options:
File, Material, Units, Specifications and Help. Each item can be
activated either by clicking with the mouse or by pressing <Alt>
and the first letter of the menu item (<Alt>-F, <Alt>-M, <Alt>-U,
<Alt>-S or <Alt>-H). Clicking on the MINIMIZE button will reduce
N P S to an icon so you can run other Windows applications, but
still have quick access to N P S when required.
The client area displays a list box containing the nominal pipe
size (i.e. what the pipe is usually called in catalogs and
4
N P S Users' Guide (version 2.0w)
----------------------------------------------------------------
specifications), the class or schedule (a code number that refers
to the wall thickness of the pipe or tube), and the true outside
diameter (OD), inside diameter (ID), and wall thickness
dimensions for pipes or tubes of the selected material. The
nominal dimensions are always displayed in their customary
fashion (i.e. those found in catalog listings). The actual
dimensions can be displayed in either inches or centimetres as
selected from the UNITS menu. If the selected material contains
more entries than can be displayed on a single screen, a vertical
scroll bar will appear at the right edge of the client area.
Most pipes are displayed as NPS (nominal pipe size, also called
IPS). Pipes and tubes are also classified by wall thickness. In
most cases, this will be a 'schedule' number (such as 40, 80,
160). Other designations are ST (standard wall); XS (extra
strong); and XX (double extra strong). These numbers all relate
to the thickness of the pipe or tube wall, and thus to its
pressure retaining ability. Some materials are classified by
pressure class, such as class 150 or class 250. Again these
numbers reflect the different wall thicknesses required to hold
these pressures. BWG numbers (Birmingham wire gauge) are often
used for tube wall thickness.
The <cursor up> and <cursor down> keys or the mouse can be used
to select the pipe size for detailed data display. The <cursor
up> and <cursor down> keys will move one line at a time. For
long lists, the scroll bar can be used to quickly move from one
end of the list to the other. The currently selected entry in
the list box will by highlighted.
MENU OPTIONS
The program options are selected using the menu:
File
Selecting 'File' from the main menu will pop up a sub-menu with
two items:
About will display a dialog box containing program version
and copyright information.
Exit will quit N P S and return to the Windows desktop.
Materials
Most piping and tubing materials are available in a variety of
5
N P S Users' Guide (version 2.0w)
----------------------------------------------------------------
sizes. However, not all sizes are available in all materials and
some materials have non-standard sizing designations or other
special characteristics. Recognizing this, N P S allows the user
to select from among a list of common piping materials.
Selecting 'Materials' from the main menu will open the MATERIALS
dialog box. This dialog box will have a list of all materials
supported by the current data file version. The materials will
be listed in alphabetical order. The currently selected material
will be highlighted.
To select and display a new material, use the <cursor up> and
<cursor down> keys or click on the desired entry then click on OK
or press <Enter>; or double click on the desired entry in the
list box. To move quickly from one end of the list to the other,
you can use the scroll bar.
To save a material as the new system default, select the desired
material, then click on the SAVE button. This will record the
selected material in the NPS.INI file as the default for next
time N P S is started up. If the NPS.INI file does not exist,
one will be created in the same directory that the NPSW.EXE and
NPS.DTA files are located.
If you do not wish to change the currently displayed material,
click on CANCEL to return to the main window.
To display a help screen, click on the HELP button. A list of
currently supported materials and densities can be found on page
2 of the Materials Help screen. You can cycle through all of the
available help topics by clicking on the NEXT or PREV buttons in
the HELP dialog box. Click on the OK button to return to the
MATERIALS dialog box.
Units
NPS can display piping data in several different systems of
measurement. Choosing 'Units' from the main menu will open the
DISPLAY UNITS dialog box. The dimensional units can be selected
as US (pounds, inches, US gallons), UK-Imperial (pounds, inches,
Imperial gallons), or Metric (kilograms, centimetres, litres).
To SAVE the current defaults, click on the SAVE button. When you
save the defaults, N P S will automatically create the file
NPS.INI in the directory where the NPSW.EXE and NPS.DTA files
reside if it does not already exist.
If you do not wish to change the current set of display units,
6
N P S Users' Guide (version 2.0w)
----------------------------------------------------------------
click on the CANCEL button.
Specifications
Selecting 'Specifications' from the main menu will open the PIPE
SPECIFICATIONS dialog box displaying additional data for the
selected pipe size and material: weight per foot (pounds per foot
of length) or meter (kilograms per metre of length) of pipe;
cross sectional area of the bore and pipe wall (square inches or
square centimetres); inside and outside surface area of the wall
(square inches per foot of length or square centimetres per metre
of length); section modulus (inches ^ 3 or centimetres ^ 3);
moment of inertia (inches ^4 or centimetres ^ 4); radius of
gyration (inches or centimetres); and water flow capacity at 1
ft/s (or 1 m/s) in volumetric (gallons per minute or litres per
second) and mass units (pounds per hour or kilograms per hour).
The dimensions can be displayed in either inch or centimetre
units; the weights can be displayed in either pounds or
kilograms and the flow volumes can be displayed in US gallons,
Imperial gallons, or litres, depending on the settings of the
system defaults (see Units menu item, above).
To display a help screen, click on the HELP button. You can
cycle through all of the available help topics by clicking on the
NEXT or PREV buttons in the HELP dialog box. Click on the OK
button to return to the MATERIALS dialog box.
The specifications dialog box can also be opened by double
clicking on an entry in the piping size list, or by selecting an

Help
N P S contains on-line help which is available at any time N P S
is running. The help screens are built into N P S. Access to
the Windows Help facility is not required to display N P S help.
Selecting 'Help' from the main menu will pop up a HELP index sub-
menu with the following items: About, General, Materials, Piping
Specs, Registration and ASP Ombudsman.
The About selection displays the same dialog box as the File-
About menu option. Selecting any of the other options will open
the HELP dialog box and display a page of text. The HELP dialog
has 3 buttons: Next, Prev and OK. Clicking on Next or Prev (for
previous) will cycle through all of the help pages. Click on the
7
N P S Users' Guide (version 2.0w)
----------------------------------------------------------------
OK button to return to the main window.
The General sub-menu selection starts the display at the first
help page. The Materials sub-menu selection starts the display
at the same help screen as the HELP button on the MATERIALS
selection dialog box. The Piping Specs sub-menu selection starts
the display at the same help screen as the HELP button on the
PIPE SPECIFICATIONS dialog box. The Registration sub-menu
selection starts the display at the registration information
screen and the ASP Ombudsman sub-menu selection begins at the ASP
ombudsman message screen.
DATA FILES
NPS.DTA
The NPS.DTA file contains data on the name, thickness class code,
inside and outside diameter for each nominal pipe size, and the
name and density of each material in inch-pound units. All other
parameters (wall thickness, weight, areas, flow capacity and all
metric values) are calculated from these numbers. Details of the
calculations are summarized in APPENDIX A. The linear weight of
pipe is calculated based on a nominal density for the selected
material. Weights for other materials can be estimated by
multiplying the given weight by the ratio of the material's
density to the given density.
The data are stored in a proprietary format which cannot be
changed by the user. The data used in N P S has been compiled
from a wide variety of industry standards. While great care has
been taken to ensure the accuracy of the data, Herne Data Systems
Ltd. assumes no liability for errors or omissions.
* * * *
If you have the piping specifications for a material
which is not included in this list, please forward it
to Herne Data Systems Ltd. If we include it in the
next version, we will send you a free update.
* * * *
NPS.INI
The NPS.INI file contains program defaults for the material and
display units. The file is structured according to a standard
8
N P S Users' Guide (version 2.0w)
----------------------------------------------------------------
Windows .INI file in the format <string>=<value>. Two parameters
are currently used:
PIPETYPE defines the default pipe or tubing material. It is a
positive integer value from 0 to ??. This value is
updated each time you click on SAVE from the MATERIALS
dialog box.
UNITS defines the system of measurement used to display data.
A value of 0 indicates US customary units (inches,
pounds, feet, US gallons); 1 indicates Imperial (UK)
units (same as US except for Imperial gallons); and 2
indicates metric units (centimetres, litres,

APPENDIX A: CALCULATION METHODS
The following calculation methods are used in N P S. (All units are
normalized by N P S to ensure dimensional correctness).
wall_thickness = (outside_diameter - inside_diameter) / 2
bore_area = (pi / 4) x (inside_diameter) ^ 2
wall_area = [(pi / 4) x (outside_diameter) ^ 2] - bore_area
linear_weight = wall_area x unit_length x material_density
section_modulus = pi x [(outside_diameter^4) - (inside_diameter^4)]
-------------------------------------------------
[32 x outside_diameter]
moment_of_inertia = pi x [(outside_diameter^4) - (inside_diameter^4)]
-------------------------------------------------
64
radius_of_gyration = [(outside_diameter^2) + (inside_diameter^2)] ^0.5
-------------------------------------------------
4
material_density = density of the piping material. For a list of the
densities used, see the HELP screen on the main N P S
program.
vol_flow_capacity = bore_area x flow_velocity
mass_flow_capacity = vol_flow_capacity x water_density
flow_velocity = 1 foot/second for US and Imperial units
= 1 metre/second for Metric units
water_density = 0.03613 pounds/cubic inch for US and Imperial units
= 1 gram/cubic centimetre for Metric units
10
N P S Users' Guide (version 2.0w)
----------------------------------------------------------------
The following constants are used for conversions between US,
Imperial and Metric units:
1 foot = 0.3048 metre
1 inch = 2.54 cm
1 US gal = 3.785 litres
1 Imp gal = 4.54 litres
1 pound = 0.454 kg
