During the test of a centrifugal pump, water was drawn steadily from a reservoir through a vertical 30 cm diameter suction pipe, and the pump discharged the water into a horizontal 25 cm diameter delivery pipe. A Bourdon pressure gauge just outside the casing on the suction pipe read −0.4 bar gauge while the discharge pressure gauge indicated a pressure of 2.8 bar gauge. A vertical distance of 1.5 m intervened between the pipe centers at the sections where the gauges were attached. If the water discharge through the arrangement was measured as 0.1 m3⁄s, compute the power expended in running the pump.
Correct answer is 'Range: 33 to 34'. Can you explain this answer?
Verified Answer
During the test of a centrifugal pump, water was drawn steadily from ...
Let H be the head that pump adds to the water, since the total head of outlet of pump>Total head at inlet
P2 = 2.8 × 105
Z1 = 0 ; Z2 = 1.5 m
Applying continuity equation at inlet and outlet
solving the above for V1 and V2
Substituting values we get
32.61 + 0.031 + 1.5 = H = 34.14m/s
We know, power delivered by pump
=pQgH = 102 x 0.1 x 9.81 x 34.14
=33.49 kW
Assuming 100% pump efficiency
Power delivered = power consumed
= 33.5 kW
