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?
what is a positive displacement pump? In what ways does it differ from a centrifugal pump.
if the pump flow rate in a simple hydraulic system is 10 gmp and the maximum system pressure is 3,000 psi, what size reservoir and conductors for pump inlet and working lines would you choose to install? why?
