A Rankine cycle with reheat operates between 20 kpa & 12.5 Mpa with a reheat occurring at 1.2Mpa. Steam enters both the high and low pressure turbine at 500 C, and the enthalpy of steam at the exit of high and low pressure turbines are 3050 and 2600 Kj/Kg. the pump has an efficiency of 75%. Please determine: (a) the net work output, (b) the thermal efficiency, and (c) the back work ratio and (d) draw and label the T-s diagram.
