The equations of motion of a viscous Newtonian fluid between 
rotating and stationary conical coaxial permeable surfaces have been 
obtained from the Navier-Stokes differential equations and have 
been solved by the numerical method. The analytical dependences confirmed 
experimentally for determination of the energy consumption in rotary 
apparatuses have been obtained.
