Extracted text: Q 3)In a Rankine cycle with reheat steam leaves the boiler at 17.5 MPa and 500°C, and then it is isentropically expanded through a high-pressure turbine to 3 MPa. It is reheated at constant pressure to 500°C and isentropically expanded through a low-pressure turbine to 70 kPa. The steam is then condensed to saturated liquid at 70 kPa and isentropically compressed to 17.5 MPa to repeat the cycle. a. Draw the cycle on a T-s diagram. b. Determine the heat added. e. Determine the heat rejected. d. Determine the thermal effi ciency of the cycle.
