Water in a cylinder of height 12 ft and radius 3 ft is to be pumped out. The density of water is 62.4 lb/ft³. Find the work required if (a) The tank is full of water and the water is to be pumped over the top of the tank. Work = (include units) (b) The tank is full of water and the water must be pumped to a height 4 ft above the top of the tank. Work = (include units) (c) The depth of water in the tank is 7 ft and the water must be pumped over the top of the tank. Work = (include units)
