The pump shown draws water from reservoir A at elevation 10 m and lifts it to reservoir B at elevation 60 m. The loss of head from A to 1 is two times the velocity head in the 200 mm diameter pipe and the loss of head from 2 to B is ten times the velocity head in the 150 mm diameter pipe. Determine the rated horsepower of the pump and the pressure heads at 1 and 2 in meters when the discharge is 0.03 m3/sec.
