In an axial flow pump, the rotor has an outer diameter of 75 cm and an inner diameter of 40 cm; it rotates at 500 rpm. At the mean blade radius, the inlet blade angle is 12° and the outlet blade angle is 15°. Sketch the corresponding velocity diagrams at inlet and outlet, and estimate from them (1) the head the pump will generate, (2) the discharge or rate of flow in 1/s, (3) the shaft h.p. input required to drive the pump, and (4) the specific speed of the pump. Assume a manometric or hydraulic efficiency of 88% and a gross or overall efficiency of 81%.
