The impeller of a centrifugal pump is 0.3m in diameter and runs at 1450rpm. the pressure gauges on suction and delivery sides show the difference of 25m. the blades are curved back to an angle of 30 ° . the velocity of flow through impeller, being constant, equals to 2.5m/s, find the manometric efficiency of the pump. if the frictional losses in impeller amounts to 2m, find the fraction of total energy which is converted into pressure energy by impeller. also find the pressure rise in pump casing.
