The relationship between μ*ξ and T R for nonpolar gases at normal pressures is used to predict the viscosity for their mixtures. For such mixtures, pseudocritical temperatures are used to obtain T R . To establish ξ m for a mixture, a binary interaction model has been applied that utilizes composition and the ξ values of the pure components. Viscosities have been calculated for twenty binary systems which include helium and hydrogen. These calculated values produce an average deviation of 1.97% for 148 compositions. This method was also applied to the helium‐neon‐argon ternary system at 100°C. to obtain for four mixtures examined an average deviation of 2.2%.
