Tension on the External and Internal Surface of the Rotating Cylindrical Cover Partially the Filled Liquid

Abstract

It is considered movements of a layer of viscous liquid on an internal and external surface of a rotating cylindrical cover in the field of forces of inertia, a superficial tension and weight. The equations of evolution of free border of a layer are received. On the basis of the solution of a non"stationary hydrodynamic task pressure upon surfaces of a rotating cylindrical cover is found.
