Abstract: The method for calculating viscosity and mutual diffusion coefficients of rarefied binary gas mixtures for various temperatures and compositions of the mixture is proposed on the basis of the molecular-kinetic theory of gases. The results of the calculation of viscosity of carbon dioxide with ethane and carbon dioxide with propane in the temperature range 250-1200 K for different mixtures compositions and also for the equimolar mixtures of these gases in the same temperature range are presented. The obtained values of the properties are compared with the calculated and experimental results of other authors.

Keywords: gas mixtures, viscosity, diffusion, calculation method.
