Underground water needs to be pumped into a pool

The school decides to create a new Fluids test facility on the lab building roof. Underground water needs to be pumped bu a 73% efficient 5.0-kW submerged pump to the facility, which has a free surface h=30 m above the underground water level. The diameter of the pipe is 7.0 cm on the intake side and 5.0 cm on the discharge side.

Assume the elevation difference between the pump inlet and the outlet and the effect of the kinetic energy correction factors to be negligible.

a) Determine the maximum flow rate of water.

b) Determine the pressure difference across the pump.

    (5) Oil is being pumped from a refinery to a distribution center. The pipe has a length L 1000 m, diameter D-30 cm, and friction factor f-0.015. The change in elevation between the refinery and distribution center is H-10 m up. The pump power required to pump Q-o2 m3/s is P-70 kW. Calculate the pump efficiency and the power required to pump 2Q (i.e. 0.4 m'/s). Ignore local losses including the inlet and outlet velocity head and assume that the...
