Hi, Please help me with this problem and show the full solution, Thank you very much.
Construct the ideal Rankine cycle with three stages of reheating on a T-s diagram. Assume the turbine inlet temperature is the same for all stages. Justify how does the cycle efficiency vary with the number of reheat stages.
An ideal reheat rankine cycle is characterized by a steam generator pressure of 11 MPa and a temperature of 600°C. The turbine operates in such a way that the quality of steam leaving should not be more than 0.896. If the condensing pressure is 10 kPa, what isa. the reheating pressureb. the thermal efficiency of the cycle
