WebMay 18, 2024 · With regards to the viscosity, CoolProp does a *very* approximate treatment of the viscosity. The fluidities (fluidity = 1/viscosity) are mole fraction averaged. It's not great, but the theoretical understanding of mixture viscosity is very poor. REFPROP does something slightly smarter, but even there the uncertainties are still significant. … http://www.coolprop.org/coolprop/HighLevelAPI.html
