QUESTION:

Steam enters a two-stage adiabatic turbine at \(8 M P a \text { and } 500^{\circ} C\). It expands in the first stage to a state of \(2 M P a \text { and } 350^{\circ} \mathrm{C}\). Steam is then reheated at constant pressure to a temperature of \(500^{\circ} \mathrm{C}\) before it is routed to the second stage, where it exits at  and a quality of 97 percent. The work output of the turbine is . Assuming the surroundings to be at \(25^{\circ} \mathrm{C}\), determine the reversible power output and the rate of exergy destruction within this turbine.
