Hi,I have a very dilute mixture of Air-Benzene(Benzene concentration is about 50 ppm).

How should I achieve density and viscousity of the mixture in the Fluent?
(Default values in the software are not correct for me, because they are set for normal mixture)

By Henry law?How?

Sorry,I think that I didn't express my purpose well,

I want to calculate the properties of dilute mixture and then enter them to the software by editing existing properties,
But I don't know the formulation for dilute mixtures.
