Steam is supplied to a two-stage turbine at 40 bar and 350°C. It expands isentropic ally until it is just dry-saturated. Then it is reheated to 350°C at constant pressure and expanded in the second-stage turbine to the condenser pressure of 0.03 bar. If the isentropic efficiency of the second stage is 78%. Calculate the specific steam consumption and the thermal efficiency.
