Task id16450

A hollow cylinder with cross-sectional area S = 2.5 m2 floats in kerosene. In order for the cylinder to float in water with the same draft (immersion depth), a load of mass m = 100 kg must be placed in it. Find the mass of the cylinder M and the depth h of its immersion. Kerosene density pk = 0.8·103 kg/m3.
