Water enters a hydraulic turbine through a 30-cm-diameter pipe at a rate of 0.5 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. take the density of water to be 1000 kg/m3 and the density of mercury to be 13,560 kg/m3.
