A centrifugal pump has a suction pipe with a diameter of 100 mm, and a delivery pipe with a diameter of 75 mm. When discharging 15 L s -1 of water, the inlet water pressure recorded is a vacuum of 198 mm Hg. The delivery pressure gauge, placed at 200 mm above the pump inlet, recorded apressure of 0.95 bar. As a reminder: 1 bar = 750 mm Hg density of water = 1000 kg m -3 Calculate the total head losses, Ht (i.e., the rise in total head) and considering that the measured input power is 3.2 kW, calculate the pump efficiency

Question
A centrifugal pump has a suction pipe with a diameter of 100 mm, and a
delivery pipe with a diameter of 75 mm. When discharging 15 L s -1
of water, the inlet water pressure recorded is a vacuum of 198 mm Hg. The delivery pressure gauge, placed at 200 mm above the pump inlet, recorded apressure of 0.95 bar.
As a reminder:
1 bar = 750 mm Hg
density of water = 1000 kg m -3
Calculate the total head losses, Ht (i.e., the rise in total head) and considering that the measured input power is 3.2 kW, calculate the
pump efficiency.
