Scenario (1)The first steam power plant operates on an ideal reheat Rankine cycle. Steam enters the first turbine at 8 MPa and 500 C and leaves at 3 MPa. Steam is then reheated at a constant pressure to 500 C before it expands to 20 kPa in the low-pressure turbine.

(Hint: You will assume different values for the isentropic turbine efficiency such as: 70%, 80%, 90%, 95%, and 100%, then observe how it will change the thermal efficiency of the cycle).
