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.
