What is the horsepower requirement for a water pump, if the required flow rate is 200 gpm and the required pressure increase assigned to the pump is 32 psi?
The characteristics of a particular pump are shown in the image below. Calculate the head and discharge one would get at maximum efficiency if the size was doubled and the speed was halved.
A centrifugal pump driven by a 160-hp motor rotating at 2400 rpm is used to pump 70°F water in a manufacturing plant. The pump operates against a head of 100 ft and has an efficiency of 70%. If this pump is used under a head of 196 ft, what power will be required?
