Question

Water is being raised from a reservoir A (elev. 0) to reservoir B (elev. 825) using a pump at elevation -25m. The frictional losses from reservoir A is 4 times the velocity head while the frictional losses from the exit of the pump to reservoir B is 22 times its velocity head. Pipe A to the pump is 100 mm in diameter. Pipe from the pump to reservoir B is 90 mm in diameter. The total flow is 220 liters per hour.
1. Compute the output power of the pump in kilowatts.
a. 571 kW
b. 600 kW
c. 564 kW
d. 497 kW
2. Compute the pressure head at the entrance of the pump.
a. 12.659 m
b. 12.771 m
c. 12.663 m
d. 14.752 m
3.Compute the pressure head of the water as it exits the pump.
a. 311.659 m
b. 953.340 m
c. 322.859 m
d. 901.459 m
