HYDROSTATIC HEAD CORRECTION

W. Kolaczia

Abstract

The volume of a cylindrical storage tank with a vertical axis changes - besides of the influence of other quantities - with the hydrostatic pressure applied by the liquid stored in the tank. The formula of M. K. Sayadi describes the influence of the liquid head on the expansion of storage tanks best having the handicap that it can be evaluated individually for each tank only by means of a numerical program because the explicit solution works only for a tank consisting of a single course. The author tried to meet two requirements: to give a formula for an explicit solution for tanks consisting of several courses and – to give a formula which leads to a result as accurate as that one obtained by numerical solution according to the formula of Sayadi. Both conditions are fulfilled by the formula derived.
