The problems of studying viscosity are encountered in technology, in the development of technology for various production processes, in design work and design calculations related to a wide variety of liquid materials. Several areas are involved in the study of the viscosity of liquids at once: physical acoustics, hydrodynamics and the molecularkinetic theory of gases and liquids. The theoretical dependence of the viscosity of liquids on temperature is obtained based on the modified Eyring equation. Approximation of experimental data from reference materials was carried out. It is shown that most liquids of various types confirm this formula. A thorough analysis of the obtained data was carried out, and a relationship was found between the forces of intermolecular interaction and viscous flow.
