A single-stage centrifugal pump having a suction pipe 254 mm in diameter and a discharge pipe diameter of 5 inches is being tested and found out to discharge 48 lps of water. A pressure gage connected to the inlet pipe reads 118 mm Hg vacuum and a discharge gage reads 150 kPa at a distance 100 cm above the point where the inlet pressure was measured. If the kW rating of the driving motor is 12 kW, calculate: a) the pump efficiency. b) if this pump runs at 1800 rpm, what will be the new discharge rate, head, and power developed if the pump speed was increased to 3600 rpm? Assume constant efficiency. c) Determine the pump type.

Question
A single-stage centrifugal pump having a suction pipe 254 mm in diameter and
a discharge pipe diameter of 5 inches is being tested and found out to discharge 48 lps of
water. A pressure gage connected to the inlet pipe reads 118 mm Hg vacuum and a
discharge gage reads 150 kPa at a distance 100 cm above the point where the inlet
pressure was measured. If the kW rating of the driving motor is 12 kW, calculate:
a) the pump efficiency.
b) if this pump runs at 1800 rpm, what will be the new discharge rate,
head, and power developed if the pump speed was increased to 3600 rpm? Assume
constant efficiency.
c) Determine the pump type.
