A reheat steam cycle has 13500 kPa throttle pressure at the turbine inlet and 2800 kPa reheat pressure. The throttle and reheat temperature of the steam is 540°C. The condenser pressure is 3.4 kPa. Find the cycle thermal efficiency in %. Note: At 13.5 MPa, tsat 333.88 deg C, sf = 3.5921 kJ/kg-K, Sg = 5.4022 kJ/kg-K. If the steam table is needed, please use the green book entitled "Thermodynamics Properties of Water Including Vapor, Liquid, and Solid Phases" by Keenan, Keyes, Hill, and Moore.
