Question
Steam is supplied to a two-stage turbine at 48 bar and 400 °C. It expands in the first
turbine until it is just dry saturated, then it is re-heated to 400 °C and expanded through the second-stage turbine. The condenser pressure is 0.04 bar.
what is the temperature in degrees celcius at state 4?
find the thermal efficiency of the system in percentage to 2.d.p?
