Steam is supplied to a two-stage turbine at 40 bar and 350 o It expands in the first turbine until it is just dry saturated, then it is reheated to 350 oC and expanded through the second stage turbine; the isentropic efficiencies of the first and second stage turbines are 84 % and 78 % respectively. The condenser pressure is 0.035 bar. Sketch the process on a T-s diagram and calculate; i. The work output and heat supplied per kg of steam for the plant assuming ideal processes ii. The thermal efficiency of the cycle iii. The specific steam consumption
