The authors use an extended form of the modified Enskog Theory (MET) to calculate viscosity and mutual diffusion coefficients for several binary mixtures. Second and third virial coefficients are required for the calculations. They find that the extended MET provides predictions of the shear viscosity for He-Ar and Ne-Ar mixtures with an accuracy of 2% at densities up to 6 mol {center dot} L{sup {minus}1}. Extended MET values of mutual diffusion coefficients of binary mixtures in which the mole fraction of one component approaches zero were calculated for He-Ar and Kr-Ar mixtures. The MET values fall within 10-15% of the experimental data at densities up to 11 mol {center dot} L{sup {minus}1}.
