Consider a reheat cycle utilizing steam. Steam leaves the boiler and enters the turbine at
4 MPa, 400◦C. After expansion in the turbine to 400 kPa, the steam is reheated to 400◦C
and then expanded in the low-pressure turbine to 10 kPa. Determine the cycle efficiency.
For each control volume analyzed, the thermodynamic model is the steam tables,
the process is steady state, and changes in kinetic and potential energies are negligible.
For the high-pressure turbine,
