If the expansion processes in the turbines of Problem 8.3 have isentropic efficiencies of 84% and 78% respectively, in the lust and second stages, calculate the work output and the heat supplied per kilogram of steam, the cycle efficiency, and the specific and consumption. Compare the efficiencies and specific steam consumption obtained from Problems 8.1, 8.2, 8.3, and 8.4. Compare also the wetness of the steam leaving the turbines in each

Problem 8.3

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.
