es 2 m from high to low tide level. The pump centerline is located 2.6 m above the surface of the water at high tide. The pump discharges into the atmospheric surface condenser, 3 m above the pump centerline. Loss of head due to friction in the suction pipe is 0.8 m and that in the discharge side is 3 m. Pump is directly coupled to a 1750 rpm, 460 volts, 3 phase, 60 Hz. Calculate:

Question
1. A centrifugal pump delivers 900 m^3/hr of sea water (sp.gr.= 1.03) from a source where
the water level varies 2 m from high to low tide level. The pump centerline is located
2.6 m above the surface of the water at high tide. The pump discharges into the
atmospheric surface condenser, 3 m above the pump centerline. Loss of head due to
friction in the suction pipe is 0.8 m and that in the discharge side is 3 m. Pump is directly
coupled to a 1750 rpm, 460 volts, 3 phase, 60 Hz.
Calculate:
a) total dynamic head
b) pump theoretical power
c) power to drive the pump if pump efficiency is 82%
