Required information. The net work output and the thermal efficiency for the Carnot and the simple ideal Rankine cycles with steam as the working fluid are to be calculated and compared. Steam enters the turbine in both cases at 10 MPa as a saturated vapor, and the condenser pressure is 50 kPa. In the Rankine cycle, the condenser exit state is saturated liquid and, in the Carnot cycle, the boiler inlet state is saturated liquid. Draw the T-s diagrams for both cycles.

A steam Rankine cycle operates with a condenser temperature of 30°C, and a boiler pressure of 15MPa. The turbine is divided into two stages, a high-pressure turbine, and a low pressure turbine.

The following is how a reheat turbine works. It takes steam with a pressure of 1560 psi and a temperature of 780 F and expands it to 430 psi.
