The shear forces and corresponding strains appearing in the flow under the action of chemical potential gradient have been analyzed. The ratios for determination of the viscosity coefficient for low-molecular pure liquids and solution components were established. It was proved that the viscosity of the low-molecular solution can be expressed via the terms of the viscosity coefficients of its components and via their concentration.
