Apparent mass of a rectangular vessel filled with liquid

The problem of an impulse applied to a rigid rectangular vessel containing an ideal incompressible liquid is solved in a form that can be conveniently used to treat short vessels. The calculation of the apparent mass of the vessel was confirmed experimentally by the method of resonance vibrations.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 1, pp. 185–188, January–February, 1980.
