Hi,

I was wondering if someone knows the thermodynamic properties (Cp, gamma, etc.) of hydrogen gas and/or point me to a reference.

Thanks a lot, Nashat

mcbride bj et al

thermodynamic properties to 6000k for 210 substances involving the first 19 elements

nasa sr3001 1963

gives polynomial coefficients.

An alternative is to Google Alex Burcat and go to the site at UC-Berkeley. That site has directions for using the polynomials and a text file with coefficients for many species.

Try- http://webbook.nist.gov/chemistry/ http://cea.grc.nasa.gov/index.html Prof. Burcat's web page (mirror): http://garfield.chem.elte.hu/Burcat/burcat.html

Thanks a lot!

The properties in the 1963 report NASA SP-3001 have been updated many times since this report.

An easy to use property generator for various species containing the most current updates (relative to the above NASA report) is found at
