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 a single pump is used to deliver water of a system which requires a total of 8 ft3/s, what is the efficiency of the pump (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 a single pump is used to deliver water of a system which requires a total of 8 ft3/s, what is the efficiency of the pump (in %)? Take the specific weight of water to be 62.4 lbf/ft3.
