6. Water enters a hydraulic turbine through a 25-cm diameter pipe at a rate of 0.6 m³/s and exits through a 30-cm diameter pipe. The pressure drop in the turbine is measured by a mercury manometer to be 1.3 m. For a combined turbine-generator efficiency of 80 percent, determine (a) the net electric power. output. (b) and pressure difference across the turbine. Disregard the effect of the kinetic energy correction factors.
