Question
Water is to be pumped from the large tank
shown in the figure below with an exit velocity
V₂ of 5.6 m/s. It was determined that the
original pump (pump 1) that supplies 1 kW of
power to the water did not produce the desired
velocity. Hence, it is proposed that an additional
pump (pump 2) be installed as indicated to
increase the flowrate to the desired value. How
much power must pump 2 add to the water?
The head loss for this flow is h = 230Q², where
hL is in m when Q is in m³/s.
Assume z = 1.8 m, A₁ = 0.06 m², A₂ = 0.03 m².
