Steam is supplied to a two-stage turbine at 40 bar and 350°C. It expands in the first turbine until it is dry saturated, then it is reheated 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 kg steam for the plant assuming ideal processes. Calculate also the cycle efficiency.
The cycle efficiency and work output of a two-stage turbine are calculated. The solution is detailed and well presented.
