- Actually, there exists a program called WaterWindows which is EXCELLENT!!!!
-
- I am an engineering student and have had extensive use with this program.
- You at least two properties (either pressure, temp, qualityuality, and maybe
- a few others I cant recall. I have had to use the three above.) and the
- program will give pretty much every thermodynamic property known to man. This
- includes the Nusselt #, Prandtl #, Reynolds #, viscosities, density, specific
- volume, entropy, enthalpy, head loss, etc. It works in both English and SI
- units. It will also tell you if you are in the subcooled region, saturated,
- or superheat region. It will also calculate all the saturated steam values:
- h-f, h-fg, h-g, s-f, s-fg, s-g, etc. Its temp and pressure range has been
- great enough that I have yet to encounter a problem with it.
- Believe me when I tell you that the program is in my opinion incredible.
- I only wish it could handle more than just water.
-
- Anyway, it is a shareware program made by TEC (not sure who they are). It is
- not all that big either, maybe a few hundred Kilobytes, if that.
- It has good graphics, as well.
- I recieved it from a friend who acquired it from his CO-OP job at a power plant
- If it was good enough from them, it is good enough for me. We checked the
- values against the steam tables in our text books and it agrees with them to
- within the 4th decimal place. However, since steam tables are all based on
- a certain reference point, it is necessary to check the program's validity
- against one's own printed tables.
-
- I am not sure of where it could be gotten outside of the Worcester, Ma area.
- I do however know of two bulletin boards which carry it in Worcester, Ma.
- Their telephaone #'s are: IDEAL STUDIES (508) 757-1806
- A GREAT SCIENCE/ENGINEERING/MATH/FRACTAL BASED BBS
-
-
- THE NUCLEUS (508) 791-6664
- TRITEL BBS WITH A PRETTY EXTENSIVE FILE BASE.
-
- I would also consider making copies of the program myself for you if I were
- sent a SASE with a disk of your choice (5-1/2, 3-1/4) formatted to High
- Density. If you like to go this route please contact me via e-mail.
- My address is murpup@wpi.wpi.edu. E-mail would be much faster since I
- check my e-mail much more than I read this group (everyday as opposed to
- once per every 1-2 weeks).
-
- Anyhow , if you have any questions, you know where to reach me.
