Transport Properties of Nine Binary and Two Ternary Mixtures of Gases at Low Density

The paper analyses earlier data on the viscosity of binary and ternary mixtures in terms of the extended law of corresponding states due to Kestin, Ro, and Wakeham (KRW). The binary mixtures involve CO 2 and CH 4 with each other, and each with He, Ne, Ar, N 2 . The ternary mixtures are: N 2 ArCO 2 and CH 4 N 2 CO 2 . Measurements fully corroborate the efficiency of the KRW law for the calculation of viscosity and binary diffusion coefficient of the simpler polyatomic gases, as expected from theory. The paper contains short tables of the viscosity and binary diffusion coefficients for the nine binary systems under consideration.
