32 Underground Water Density 1000 Kg M Is To Be Pumped By A Submerged Pump To A Pool Whose Free Surface Is 30 M Abov 1 (120.74 KiB) Viewed 27 times

32. Underground water (density 1000 kg/m³) is to be pumped by a submerged pump to a pool whose free surface is 30 m above the underground water level. The pump has an efficiency of 78 percent and requires an electrical input power of 5-kW. Determine (a) the volumetric flow rate of water [7 marks] (b) the pressure difference across the pump. [3 marks] Assume the elevation difference between the pump inlet and the outlet and the energy loss through the pipe to be negligible.
