A single-suction, single-stage, centrifugal pump delivers 240 lps of sea water (SG = 1.01)
from a source where the water level varies 2 meters from high tide to low tide level. The
pump centerline is located 3.0 meters above the surface of the water at high tide level.
The pump discharges into a surface condenser, 3.5 meters above the pump centerline.
Loss of head due to friction in the suction line is 0.8 meter and that in the discharge line
is 3 meters. The pump is directly coupled to a 1450 rpm, 440 volts, 3-phase, 60 Hz motor.
Determine:
a) the total dynamic head
b) the specific speed and the type of pump used; and
c) the pump brake power if the efficiency is 78 %.
