The article analyzes the existing methods of rationing the electrical consumption of industrial enterprises. The results of the analysis of the state of normalization of electric consumption in the ferrous metallurgy industry are given. The developed multilevel structure of normalization of electric consumption by results of research which gives prospects of definition of possibility of energy saving on considered object is described.

It is known that the application of the vector operation rot to the equations of hydrodynamics leads to the Helmholtz-Friedman equation for a vortex. A dispersed mixture, tensor transformations are used, in a certain sense generalizing the vector operation rot, which gives more than one, a couple of equations. One of them describes the transfer of vorticity is the well-known Helmholtz-Friedman equation. The second equation was obtained for the first time, and it describes the transfer of the strain rate tensor. Any tensor decomposes into symmetric and antisymmetric parts. By definition, the symmetric part of the tensor U is the strain rate tensor. The antisymmetric part of U is a tensor whose components are related in a known manner to the pseudovector angular velocity.
