A Rankine cycle with reheat operates with steam at 12 MPa and 580°C entering the high-pressure turbine. After expansion to 2.5 MPa, the steam is reheated to 580°C before entering the low-pressure turbine, which exhausts at 12 kPa. If the cycle thermal efficiency is 42% and the net work output is 1350 kJ/kg, what is the total heat input per kg of steam?
