3. A Rankine cycle operates between the pressures X5[kPa] and X6[MPa] and the heat supplied is X7[MW]. The turbine's inlet temperature is 600C, and the water enters the pump as a condensed liquid. a. Calculate the efficiency of the cycle, (10%) b. Calculate net power output, and (10\%) c. Describe how the power output would be affected if we install a geothermal heat exchanger to preheat the water before it enters the boiler. (5\%)
