Empirical and Semi-theoretical Methods for Predicting the Viscosity of Binary n-Alkane Mixtures

摘要: In this study, empirical and semi-theoretical methods for predicting the viscosity of binary mixtures n-alkanes are presented at atmospheric pressure in temperature range from 288 to 333 K. calculation method, a modified version Andrade equation simple mixture rule used. The proposed method employs both Enskog’s hard-sphere theory dense fluids principle corresponding states. viscosities n-heptane with n-hexane n-nonane covering different compositions were calculated using these which require only critical properties normal boiling point as input data. predictions compared accurate experimental data literature. Highly satisfactory results obtained. percent average absolute deviations amount 1.2 0.9% utilizing methods, respectively, 27 points.
