Viscosity of Binary Mixtures

Abstract

SEVERAL attempts have been made to represent the viscosity,, of a mixture, as a function of the concentrations, c₁ and c₂, and the viscosities, ₁ and ₂ of the components. So far as we are aware, all investigators (with the exception of Dolezalek) have used the general form: with various expressions for f, such as f = log (Arrhenius), f = 1/ (Bingham), f = ^1/3 (Kendall and Monroe). The latter demonstrated very clearly that, with any of these functions, deviations up to 20 per cent and more appear, when used for mixtures of two liquids with very different physical constants. As a matter of fact, there is no reason to suppose that any expression of this general form can give satisfaction.
