a centrifugal pump has an impeller of outer diameter 230mm and an inner diameter of 150mm. The width of the impeller at the exit is 10mm. The exit angle of the impeller is 45degrees. The velocity of flow through the impeller is constant. If the rotational speed is 960rpm, the flow rate is 0.04cubic meters per second, and the velocity in the discharge pipe is 3.26m/s. Calculate
2.1) the inlet angle of the impeller
2.2) the exit angle of the water when leaving the impeller
2.3) the total pressure head increase across the pump if it assumed that the diffuser efficiency is 62%. Ignore losses in the impeller.
