Consider a steam power plant operating on the ideal Rankine cycle. Steam enters the turbine at 3 MPa and 350°C and is condensed in the condenser at a pressure of 10 kPa. Determine the thermal efficiency of this power plant, the thermal efficiency if steam is superheated to 600°C instead of 350°C, and the thermal efficiency if the boiler pressure is raised to 15 MPa while the turbine inlet temperature is maintained at 600°C. Draw the T-S diagram of each condition.
