Problem 3. Rankine Cycle (90 points) A steam power plant operates with high pressure of 4 MPa and has a boiler exit at 600°C receiving heat from a 700° C reservoir. The ambient air at 20°C provides cooling to maintain the water/vapor mixture in the condenser at 60°C. All components are ideal (i.e., reversible) except the turbine which has an efficiency 92% ofa reversible isentropic process. Other than the irreversibility of the turbine, the power plant can be considered as...
