Help Pleaseee
Water in a vertical cylinder of height 9 ft and radius 5 ft is to be pumped out. The density of water is 62.4 lb/ ft3. Find the exact work required under each of the following conditions. The tank is full of water and the water is to be pumped over the top of the tank. The tank is full of water and the water must be pumped to a height 2 ft above the top of the tank. The depth of the water in the tank is 7 ft and the water must be pumped over the top of the tank. A fuel oil tank is an upright cylinder, buried so that its circular top is ten feet beneath ground level. The tank has a radius of 5 feet and is 15 feet high, although the current oil level is only 8 feet deep. Calculate the work required to pump all of the oil to the surface. The density of oil is 50 lb/ft3.Explanation / Answer
a].The work required is given by:
W = mgH
where,
mass of water: m = ?V
water density: ? = 62.4lb/ft^3
cylindrical tank volume: V = ?r
