✦ Synopsis

The relationship between p * t and TR for nonpolar gases a t normal pressures is used to predict the viscosity for their mixtures. For such mixtures, pseudocritical temperatures are used t o obtain TR. T o establish tm for a mixture, a binary interaction model has been applied that utilizes composition and the 5 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 a t 100°C. to obtain for four mixtures examined a n average deviation of 2.2%.
