A power plant is to be designed to run a Rankine cycle. The high-pressure side operates at 7800 kPa and the low-pressure side operates at 100 kPa. The steam leaves the turbine with a quality of 90%. You can assume that the water leaving the condenser is saturated liquid. a. What is the temperature of the steam (in C) leaving the boiler? b. What is the heat input to the boiler in kJ/kg? c. What is the work done by the turbine in kJ/kg? d. What is the heat removed by the condenser in kJ/kg? e. What is the work done by the pump in kJ/kg? f. What is the overall efficiency (in %) of the process?
