A supercritical reheat Rankine cycle has two stages of reheat. The steam state entering the high-pressure turbine is 30 MPa and 550°C. The steam expands to 5 MPa and is reheated to 450°C, reenters and expands to 1000 kPa, and is reheated to 400°C. It reenters the turbine and exhausts at 7.5 kPa. Determine (a) the quality or degrees of superheat of the steam entering the condenser; (b) the net work; (c) the cycle thermal efficiency.
