    I am searching for the physical properties of a binary gaseous mixture.

    In particular, I would want to know the local viscosity [tex] \mu[/tex] and local mass diffusitivity [tex] D[/tex] of any binary mixture of gases, as a function of the local mass fraction of each other. I have not found nothing in Google,

    Thanks.

    Fred, that's excellent! The species seem to cover a wide variety from fuel/power and chemical/process industries.

    I'd love to get my hands on the calculator engine. :biggrin:

    It could be very useful, but that is not what I am currently searching.

    I am looking for an analytical or experimental expression:

    [tex] \mu=\mu(Y_1,Y_2,\mu_1,\mu_2)[/tex]

    [tex] D=D(Y_1,Y_2,D_1,D_2)[/tex]

    where Y1 and Y2 represent the mass fraction of each component.

    Fred!!! Your link doesn't work now. And I need urgently a similar calculator. Do you know any other?

    Thanks!!
     
  7. mole fractions

    Just use mole fractions

    [tex] \mu_{mix} = \sum x_i \mu_i [/tex]

    Where the mole fractions can be found by using the mass fractions and the molar weights.

    Ooops. Sorry about that Clausius. I wasn't ignoring you. I didn't see your post. I hope you didn't get too much in a pinch. Do you still need a calculator like that old one?
