V, 20 To 21 1- (30 pts) As can be seen, a water pump is used to pump water from Reservoir one large reservoir to another 23-24 large reservoir that is at a higher elevation. The free surfaces of both reservoirs are exposed to atmospheric 10 pressure. summarize the system, distance Reservoir between the liquid levels is 7.85m. Diameter of the whole Pump piping system is 2.03 cm. Apart Valve from entrance and exit regions, there is a valve with a K value of 17.5. There are six elbows (90). Total length of pipe is 176.5 m. The material that is used for piping system is cast iron. Volumetric flow rate of system is 10440 cm /min. Calculate the pressure head developed by the pump. Then assuming that the pump efficiency is 0.73, calculate the power needed for the operation of the pump
