A pump operating at 1750 rpm delivering 500 gpm against a total head of 150 ft. Changes in the
piping system have increased the total head to 360 ft. At what rpm should the pump be operated
to achieve this new head at the same efficiency?
A pump draws water from
reservoir A and lifts it to
reservoir B. The loss of head
from A to 1 is 3 times the
velocity head in the 6 inch pipe
and loss of head from 2 to B is
20 times the velocity head in
the 4 inch pipe. Compute the
horsepower output of the
pump and the pressure heads
