The discharge through pump is 0.04 cu. m per sec and velocity of flow is constant and equal tp 2m/s. The internal and external diameter of an impeller of a centrifugal pump are 200 mm and 400 mm, respectively, which is running at 1000rpm. The diameters of the suction and delivery pipes are 140 mm and 90 mm respectively and suction and delivery heads are 6m (abs.) and 30m (abs.) of water respectively. If the outlet vane angle is 45 deg and power required to drive the pump is 16 kW, determine: (a) vane angle of the impeller at inlet, (b) the overall efficiency of the pump, and (c) manometric efficiency of the pump
