Abstract
A nonlinear compensation effect determining the dependence of the energy of a flow of a Newtonian liquid on the preexponent of its viscosity was detected. Empirical dependences relating the softening temperature of a Newtonian high-molecular multicomponent hydrocarbon system with the activation energy of its viscous flow have been obtained. The results obtained are supported by the statistical data and allow one to predict the dynamic viscosity of oil and coal fractions and materials based on them.
