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, ans at a level 5 m below the turbine, the pressure is 89.6 kPa. The water flow rate is 0.800 m3/s. The output of the shaft of the turbine is 658 kW.The water density is 1000 kg/m3. If the efficiency of the turbine in converting the mechanical energy given up by the fluid to the turbine shaft is 89% (nt = 0.89), calculate the friction loss in the turbine in J/kg.
