A centrifugal pump is to deliver 227 m³/hr of water from a source 4 meters below the pump to a pressure tank whose pressure is 28kg/m². Friction losses are estimated 2m in the suction line and 1m in the discharge line. The diameter of the suction pipe is 250mm and the discharge pipe is 200mm. Find the kw rating of the driving motor if the pump efficiency is 70%.

Transcribed Image Text:A centrifugal pump is to deliver 227 m³/hr of
water from a source 4 meters below the pump
to a pressure tank whose pressure is 28kg/m².
Friction losses are estimated 2m in the suction
line and 1m in the discharge line. The
diameter of the suction pipe is 250mm and the
discharge pipe is 200mm. Find the kw rating
of the driving motor if the pump efficiency is
70%.
