Di Pool G Pump Problem 2. Underground water (p=1000 kg/m³) is to be pumped by a 70-percent-efficient 7-kW submerged pump to a pool whose free surface is 35 m above the underground water level. The diameter of the pipe is 10 cm on the intake side and 7.5 cm on the discharge side. Determine (a) the maximum volumetric flow rate of water and (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. 프 35 m
