Underground water is to be pumped by a 78 percent efficient 5-kW submerged pump to a pool whose free surface is 30 m above the underground water level. Determine (a) the water volume flow rate and (b) the pressure difference across the pump. Disregard friction losses and assume that the effect of kinetic energy correction factors to be negligible.
im confused how this is done without known pump diameters

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 7373% efficient 5.05.0-kW submerged pump to the facility, which has a free surface h=3030 m above the underground water level. The diameter of the pipe is 7.07.0 cm on the intake side and 5.05.0 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...

an elevation 120 m through a 600 mm pipe where the
pressure required at the higher elevation is 172 kPa. The
source of the water and the discharge point are at
atmospheric pressure. Irrigation requirements dictate
that water must be pumped at the rate of 1m3

1. Water is pumped from a low reservoir to a high reservoir that is 20 m higher in elevation. The water is flowing at 1.5 m/s through a 305 mm internal diameter piping system. The water is at 18 degrees C. There are 1,000 m of piping, six standard 45 degree bends, two standard 90 degree bends, a branch flow tee, three gate valves, a swing check valve, a square inlet and a square outlet. The piping and valves are...
