Generating temperature- and pressure-dependent gas properties from elemental composition?

[goutham2023]

Is it possible to calculate temperature-dependent gas properties if only the elemental composition of the gas mixture is known? Specifically, I am looking to obtain properties like $C_p$, enthalpy, viscosity, and density over a specified range of temperatures and pressures.

Hi @goutham2023, elemental composition is not enough. Unless you constrain the mixture to chemical equilibrium.
In that case, you can compute equilibrium properties using mppequil, which allows for investigating equilibrium properties over a specified range of pressures and temperatures.
You can run it by using mppequil (mppequil -h to see all the output options).
