Transport properties for mixtures are not currently implemented.

This is a long time in the future. As a VERY rough estimate, you could do
mole fraction weighted fluidities, so 1/eta_mean(T,rho) =
sum(x_i/eta_i(T,rho))

Fair enough. Is that viscosity estimate something you'd be willing to add to coolprop as a stop-gap until you have time to do something better?

If not, does coolprop expose the names of the mixture components through the interface? I see the mole_fractions_vapor and liquid functions on the abstractstate, but I don't see a method to tell which component fluids those number go with. Am I just missing it?

What environment are you working from? C++?

Could you open an issue to get the component names (as a
std::vectorstd::string through the AbstractState interface?

I'm working from C#. I will add the new issue. Thanks.
