Abstract
The derived equations for correlation of viscosity of binary and ternary mixtures were tested and compared with those of McAllister, Chandramouli and Laddha. Testing on a large number of experimental data revealed that the equations for correlation of viscosity of binary mixtures are approximately as accurate as the equation of McAllister. On adding another coefficient, the relative deviations are lowered by 26-40%. Equations for correlation of viscosity of ternary mixtures are about as accurate as the equation of Chandramouli and Laddha. Analysis of viscosity curves of binary mixtures revealed a correlation between their form and the chemical nature of the components of the mixture.
