Steam at 40 bar, 500 "C flowing at the rate of 5500 kg/h expands in

ah.p. turbine to 2 bar with an isentropic efficiency of 83% A continuous supply of steam at 2 bar, 0.87 quality and a flow rate of 2700 kg/h is available from a geothermal energy source. This steam is mixed adiabatically with the hp turbine exhaust steam and the combined flow then expands in a 1.p. turbine to 0.1 bar with an isentropic efficiency of 78%. Determine the power output and the thermal efficiency of the plant. Assume that 5500 kg/h of steam is generated in the boiler at 40 bar, 500 °C from the saturated feedwater at 0.1 har Had the geothermal steam not been added, what would have been the power

output and efficiency of the plant? Neglect pump work.
