Steam is supplied to a two-stage turbine at 40 bar and 350t. It expands in the first turbine until it is just drysaturated, then it is re-heated to 350°C and expanded through the second-stage turbine. The condenser pressure is 0.035 bar. Calculate the work output and the heat supplied per kilogram of steam for the plant, assuming ideal process° and neglecting the reed pump term. Calculate also the specific steam consumption and the cycle efficiency.
