Consider a centrifugal water pump whose geometry and flow conditions are as follows: Impeller outlet radius – 2.5 cm, impeller inlet radius – 1.8 cm, impeller outlet width – 1 cm, design speed – 1800 rpm,
Consider a centrifugal water pump whose geometry and flow conditions 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 relative discharge velocities, c) theoretical power required at design flow rate and d) the theoretical pump curve
