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
