In a reheat ideal Rankine cycle, steam enters the high-pressure turbine at 9.0 MPa and 650°C. The steam expands until it becomes saturated vapor and then reheated to 550°C. It re-enters a low-pressure turbine and expands to a condenser pressure of 10 kPa. Determine the following: (a) Temperature, Pressure, and Enthalpy of the stream leaving the high-pressure turbine to be reheated (Stream 4) (b) Work generated by the two (2) turbines: (b) Work done on the pump: and (c) cycle efficiency. Note that the stream leaving the low-pressure turbine can either be a wet steam or a superheated steam. As part of your solution, fill up the table below.

In a reheat ideal Rankine cycle, steam enters the high-pressure turbine at 9.0 MPa and 650°C. The steam expands until it becomes saturated vapor and then reheated to 550°C. It re-enters a low-pressure turbine and expands to a condenser pressure of 10 kPa. Determine the
following:
(a) Temperature, Pressure, and Enthalpy of the stream leaving the high-pressure turbine to be reheated (Stream 4)
(b) Work generated by the two (2) turbines:
(b) Work done on the pump: and
(c) cycle efficiency.
Note that the stream leaving the low-pressure turbine can either be a wet steam or a superheated steam.
