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 % efficient -kW submerged pump to the facility, which has a free surface h= m above the underground water level. The diameter of the pipe is cm on the intake side and 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...

not sure how the mass flow rate is 8.47 kg/s
Water is pumped from an open reservoir to a large closed tank at a fixed pressure of 2 bar, through a vertical distance of 50 meters using a 5 kW pump. Determine the maximum flow rate of the water (in kg/s). State any assumptions you make. For this flow rate, determine the speed of the water inside a 10 cm diameter pipe. Determine also the pressure difference between the inlet...
