Reconsider Prob. 12??62. Determine the flow rate of water and the pressure difference across the pump if the irreversible head loss of the piping system is 4 m.

Data from 12-62

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. The diameter of the pipe is 7 cm on the intake side and 5 cm on the discharge side. Determine

(a) The maximum flow rate of water

(b) The pressure difference across the pump. Assume the elevation difference between the pump inlet and the outlet and the effect of the kinetic energy correction factors to be negligible.
