Hi!

Does anyone have a good reference for gas properties?

I need O2, N2, Argon, H2 and He for pressures from 1 - 40 bar abs. and Temp. from 300 - 1500 K.

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

O2, N2 and He are not so difficult, but i have almost nothing for Argon and H2.

Any help is highly apreciated!

Ralf
