Q7) A Centrifugal Pump has a suction lift of (1.5 m) and the delivery tank is (13.5 m) above the pump. The velocity of water in the delivery pipe is (1.5 m/s). The radial velocity of flow through the impeller is (3 m/s) and the tangent to the vane at exit from the impeller makes an angle of (120°) with the direction of motion. Assuming that the water enters radially and neglecting friction and other losses, find; i) The velocity of the water at exit, ii) The velocity head at exit from the impeller, iii) The pressure head at exit from the impeller, and iv) The desirable direction of the fixed guide vanes.​
