Use water as the working fluid ,apply Rankine power cycle with reheat . The first stage turbine inlet conditions are 15MPa and 600 C. All the turbines are known to have isentropic efficiency of 95%, however the pump is assumed as an isentropic pump. If the maximum temperature is kept at 500 C and the condenser pressure is 5 kPa, by constructing a suitable plot, show that having more than 2 reheat stages is not practical. (Hint: Take at least three reheat pressures between 3 to 13 MPa)

Hello, the cycle is violating the second law of thermodynamics.

So the cycle is practically not possible.

Thank you,

Please give a thumb up .

A reheat Rankine cycle operates with water as the working fluid. Steam enters the first turbine at 8 MPa and 450◦C and exits at 0.8 MPa. It is then reheated at 400◦C before entering the second turbine, where it exits at 10 kPa. If the amount of work into the pump is 8.04 kJ/kg and the net work per cycle produced is 1410.5 kJ/kg, determine the thermal efficiency. Assume no pressure losses in the condenser or the boiler.
