The impeller of a centrifugal pump has an external diameter of 450mm and an internal diameter of 250mm. When running, a constant radial velocity flows through the impeller at 0.5m/s. If the inlet and outlet vane angle are 15° and 35°, determine: 1. The angular velocity, and (i) [5 marks] ii) The Euler's head.
