Water enters a hydraulic turbine through a 30-cm diameter pipe at a rate of 0.6 m3/s and exits through a 25-cm diameter pipe. The pressure drop in the turbine is measured by a mercury manometer to be 1.2 m. For a combined turbine-generator efficiency of 83 percent, determine the net electric power output. Disregard the effect of the kinetic energy correction factors. 30 cm Turbine Generator 25 cm AP = 1.2 m Hg Example 35 A submersible pump (shaft power = 5 kW and efficiency = 72%) is used to pump water from a lake to a pool through a constant diameter pipe. The free surface of the pool is 25 m above the free surface of the lake. If the irreversible head loss in the piping system is 4 m, determine (a) the discharge rate of water and (b) the pressure difference across the pump. %3D Pool 25 m Water enters a hydraulic turbine through a 30-cm diameter pipe at a rate of 0.6 m3/s and exits through a 25-cm diameter pipe.
