Description

Abstract – On the basis of four different models, the theoretical estimation of viscosity of multicomponent liquid mixtures has been carried out. The mixture under the present investigation is a regular pseudo binary system, all the systems of an oxygenate (acetone, diisopropylether, methyl ethyl ketone, ethanol) interacting with a five component hydrocarbon mixtures containing 25 mol % hexane, 10 mol % heptane, 35 mol % 2,2,4-trimethylpentane, 20 mol % toluene and 10 mol % p-xylene. The six component mixture has been considered as a pseudo binary system. In order to carry out a comparative study, Kendall – Munroe, Bingham and Additive equations have been employed. Furthermore, highlight of the work is the computation of the viscosity by using the scarcely employed Sutherland relation in conjunction with aforementioned viscosity models.
