A certain Geothermal Power Plant shows that 1,700,000 kg/hr of pressurized ground water is available at 17.5MPa and 330°C. The water will be throttled to a pressure of 1.7MPa to produce wet steam and this mixture will be passed through a water separator to remove the water droplets so that saturated steam at 1.7MPa is available at the entrance of the Turbine. Other data are as follows: Discharge Pressure of turbine = 85kPa-Vac; Turbine Efficiency = 73%. Mechanical Loss = 2% of shaft power. Generator Efficiency = 95%. Determine the following:
