Water is being pumped into a storage tank that is 25 ft higher than the supply tank. If the fill rate is 5000 lbm/hr and flows through a 6-inch diameter pipe with a frictional head loss of 4 feet, calculate the feet of head that must be added by the fill pump. Assume the density of the water is 62.4 lbm/ft3 and the fill pump is at the same elevation as the supply tank.
