A 1/4-scale model centrifugal pump is tested to pump water with density of 1000 kg/m under a head of 7.5 m at speed of 500 rpm. It was found that 7.5 kW was needed to drive the model. Assuming the pumps is geometrical similar and similar mechanical efficiency, determine; (i) speed and power required by the prototype when pumping against a head of 44 m; ratio of the discharges between model and prototype; and head, capacity and power coefficient of...
