A pump is required for a U.S. fie ld application with the following specifications: a flow rate
of I 2.5 cfs (ft 3/ sec) against a head of 95 ft. To design the pump, a model is built with a 6 in. diameter impeller and tested under optimum conditions. The test results show that at aspeed of I , 150 rpm the pump requires 3. 1 hp to discharge 1 cfs against a head of 1 8 ft. Determine the power requirement, diameter, and speed of a geometrically similar pump for the field.
