Apump draws water through an 8 in. suction pipe and discharges it through a 4 in. pipe in which the velocity is 12 ft/s. the 4 in. pipe discharges horizontally into air at c. to what height h above the water surface at a can the water be raised if 21 hp is delivered to the pump? assume that the pump operates at 60% efficiency and that the head loss in the pipe between a and c is equal to 2v²c/2g. assume α = 1.0 at all locations.
