A certain centrifugal pump was tested and its performance curves can be approximated as follows: H = 340 - 1.2(Q2), in feet BP = (0.0521Q3) + (1.25Q2) + (11.042Q) + 134.5, in horsepower where Q is in ft3/s. If two of this pump is connected in series to deliver water to a system whose head requirement is 615 ft, what will be the operating discharge rate in ft3/s of either pumps? Assuming the head is equally divided between the two pumps, what is the efficiency of either pumps (in %)? Take the specific weight of water to be 62.4 lbf/ft3.

Question
A certain centrifugal pump was tested and its performance curves can be approximated as follows:
H = 340 - 1.2(Q2), in feet
BP = (0.0521Q3) + (1.25Q2) + (11.042Q) + 134.5, in horsepower
where Q is in ft3/s.
If two of this pump is connected in series to deliver water to a system whose head requirement is 615 ft, what will be the operating discharge rate in ft3/s of either pumps? Assuming the head is equally divided between the two pumps, what is the efficiency of either pumps (in %)? Take the specific weight of water to be 62.4 lbf/ft3.
