Viscosity of Molecular Newtonian Liquids

Viscosity of Molecular Newtonian Liquids

An empirical expression based on the general notions of available structural and diffusion theories of viscous flows has been proposed for the viscosity coefficients of molecular liquids. The proposed expression determines the relation between the viscosity coefficient, self-diffusion coefficient, s...

Description
Summary:An empirical expression based on the general notions of available structural and diffusion theories of viscous flows has been proposed for the viscosity coefficients of molecular liquids. The proposed expression determines the relation between the viscosity coefficient, self-diffusion coefficient, surface tension coefficient, and steric parameter of liquid molecules. The validity of the proposed expression has been confirmed by its applicability to some liquids having different physicochemical characteristics.
