Abstract

The kind of a hydrostatic equation for the vertical elastic tank, for example, a fuel tank of a rocket on a starting table is proved. The hydrostatic equation is received on the basis of specified Bernoullis equation. The substantiation is lead with the help of Laplaces formula for pressure under an elastic surface of a liquid which can arise both due to forces of a superficial tension, and due to an elastic thin-walled shell as in the present task. The form of the vertical elastic tank with a rigid bottom and the rigid top band, filled with a lied liquid is received. It is shown that it is necessary to use special record of the Gooks law for reception of the form of the tank. The analysis of this form is carried out. Distribution on height of the tank of hydrostatic pressure, volumetric density of energy of the stretched elastic wall, and also the sum of these sizes is shown. Hydrostatic pressure at which level there is a maximal increase in the area of the elastic tank is found.
