Consider a centrifugal water pump whose geometry and flowconditions are as follows: Impeller outlet radius – 2.5 cm,impeller inlet radius – 1.8 cm, impeller outlet width – 1 cm,design speed – 1800 rpm, Design flow rate120 liters/min,Backward-curved vanes (outlet blade angles) – 60 deg. Assuming 100%efficiency, find: a) the total head, b) absolute and relativedischarge velocities, c) theoretical power required at design flowrate and d) the theoretical pump curve
