Why don't you use the standard steam tables? If you want them in digitized form a quick search at google will give you many links.

Hi

Check out the following links

Well with half minute google search I found these links.

I hope this helps.

Carlo/abhishek/Ali:

I have continually been advising engineers about the existence of a FREE, authoritative, and detailed thermodynamic properties database.

The National Institute of Standards and Technology (NIST), an official branch of the US government, operates this Website at:

http://webbook.nist....hemistry/fluid/

How much more authoritative can you get? This website gives FREE thermodynamic data on Thermophysical Properties of Fluid Systems and accurate thermophysical properties are available for 34 fluids including water (steam). These data include the following:

Density
Cp
Enthalpy
Internal energy
Viscosity
Joule-Thomson coefficient
Specific volume
Cv
Entropy
Speed of Sound
Thermal conductivity
Surface tension (saturation curve only)

I normally download the data in HTML tables and paste these directly into Excel. Once on a spreadsheet, I employ one of my regression programs and generate an equation for the data. I have found this method to be very accurate and quick.

Thanks Art for the link to NIST. The database is great and was something I was looking for.

umm... very very simple thing to do. use a simulator like hysys. its amazingly fast while calculating properties of various streams... no matter what components you have.
