Water is stored in an elevated reservoir. To generate power, water flows from this reservoir down through a large conduit to a turbine and then through a similar-sized conduit. At a point in the conduit 89.5 m above the turbine, the pressure is 172.4 kPa and at a level 5 m below the turbine, the pressure is 89.6 kPa The water flow rate is 0.800ms The output of the shaft the turbine is 658 kW. The water density is 1000 ke m. If the efficiency of the turbine in converting the mechanical energy gven up by the fluid to the turbine shaft is 89 % (n =0.89). a) Draw a schematic diagram for the process b) Calculate the frictional loss in the turbine in J kg %3D
