3. A pump draws water at 300 liters per second from reservoir A and lifts it to reservoir B as shown. The head loss from A to 1 is 20 times the velocity head in the 200 mm diameter and the head loss from 2 to B is 20 times the velocity head in the 150-mm diameter pipe. Assume your own reservoir B elevation then compute for the energy that must be supplied to the pump in kW if said appurtenance has an efficiency of 80%. Compute also the pressure at points 1 and 2. Reservoir A 200 mm pipe Elevation=-20 m Point 1 Point 2 Pump 150 mm Reservoir B

Transcribed Image Text:3. A pump draws water at 300 liters per second from reservoir A and lifts it
to reservoir B as shown. The head loss from A to 1 is 20 times the velocity
head in the 200 mm diameter and the head loss from 2 to B is 20 times the
velocity head in the 150-mm diameter pipe. Assume your own reservoir B
elevation then compute for the energy that must be supplied to the pump
in kW if said appurtenance has an efficiency of 80%. Compute also the
pressure at points 1 and 2.
