Gas Properties for Argon and Hydrogen at high Temp
 

Hi!

Does anyone have a good reference for the properties of Argon and Hydrogen at higher Temperatures and pressure? The only values i found ( like at http://webbook.nist.gov/chemistry/fluid/ ) are up to 400 K.

I need 300-1400 K and 1-20 bar!

The properties I need are: heat capacity, viscosity, density, Pr Number, heat conductivity and thermal diffusivity.

Any help is highly apreciated!

Ralf

I don't think you'll find values, however, you may find relations for density and viscosity as functions of temperature and pressure. They might be there in Sonntag's Thermodynamics book.

You may even go through PERRY's handbook
