A centrifugal pump delivers 2.5 cfs of water against a head of 25 ft at 1500 rpm and requires 10 hp. If the speed is reduced to 1250 rpm calculate the flow (in m^3/s), assuming the same efficiency.
A pump is driven by an electric motor moves 35 gal/min of water from reservoir A to reservoir B, lifting the water to a total head of 245 ft. The efficiency of the pump and motor are 64% and 84% respectively. What size of motor (HP) is required?
a. 3 hp b. 5 hp c. 4 hp d. 7 hp
