A centrifugal pump delivers 900 m3/hr of sea water of sp.gr.= 1.03 from a source wherethe water level varies 2 m from high to low tide level. The pump centerline is located2.6 m above the surface of the water at high tide. The pump discharges into theatmospheric surface condenser, 3 m above the pump centerline. Loss of head due tofriction in the suction pipe is 0.8 m and that in the discharge side is 3m. Pump is directlycoupled to a 1750 rpm, 460 volts, 3 phase, 60 Hz. Calculate: a) total dynamic head b) pump theoretical power
