Question

Water is pumped from a large reservoir to a point 20 m higher than the reservoir.

Calculate the pump head if 0.01 m3/s flows through a 0.15 m diameter pipe and the

total frictional head loss is given to be 35^2/2g?

Answer 1

A pump draws water from reservoir A and lifts it to reservoir B as shown in Figure 4-10. The loss of head from A to 1 is 3 times the velocity head in the 150-mm pipe and the loss of head from 2 to B is 20 times the velocity head in the 100-mm pipe. Compute the horsepower output of the pump and the pressure heads at 1 and 2 when the discharge is: (a) 12 L/s; (b) 36 L/s.
