the ideal head, the hydraulic efficiency, the power to operate the pump. d) Draw the velocity diagram at the outlet. Assume that the pump discharges 1550 Vs of water. A

centrifugal pump impeller has an outer diameter of 1.2 m; rpm 210; area at the outerperiphery 0.65 m?; angle of vane at outlet 25°, and ratio of external to internal diameter 2:1.The measured head of the pump is 6.2 m and the flow is radial at the inlet. Calculate
