A centrifugal pump provides a flow rate of 500 GPM when operating at 1760 rpm against a 200 ft head. Determine the pump's, a) Flow rate b) Developed head c) Pump power if the speed is increased to 3500 rpm?

A centrifugal pump delivers 50 liters of water per second against a total head of24 meters running at 1500 rpm. The velocity of flow is maintained constant at 2.4 m/s and the blades are curved back at 30o to the tangent at exit. The inner diameter is half of the outer diameter. If the manometric efficiency is 80%, Find: (a) blade angle at inlet, and (b) power required to drive the pump

The power output is 30 Hp to a centrifugal pump that is discharging 900 gpm and which operates at 1800 rpm against a head H=120 ft, 220 V, 3 phase, 60 Hertz. If this pump is modified to operate 1200 rpm, assuming its efficiency remains constant, determine its discharge in gpm, the theoretical head if imparts to the liquid, and the power input to the pump
