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. Determine the specific work output of the system to 3 d.p? what is the specific entalphy in kJ/kg for state 2?

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.
Determine the specific work output of the system to 3 d.p?
what is the specific entalphy in kJ/kg for state 2?
