An axial flow pump operates at 500 rev/min. the outer diameter of the impeller is 750 mm and the hub diameter is 400 mm. at the mean blade radius, the inlet blade angle is 12 degrees and the outer blade angle is 15 degrees, both measured with respect to the plane of the impeller rotation. sketch the corresponding velocity diagrams at inlet and outlet, and estimate the following: (a) the head generated by the pump. (b) the rate of flow through the pump. (c) the shaft power consumed by the pump. assume a hydraulic efficiency of 87% and an overall efficiency of 70%. volumetric efficiency may be assumed to be 1.0.
