Air is expanded in a steady flow process through a turbine. Initial conditions are \(1300^{\circ} \mathrm{C}\) and \(2.0 \mathrm{MPa}\) absolute. Final conditions are \(500^{\circ} \mathrm{C}\) and atmospheric pressure. Show this process on a Ts diagram. Evaluate the changes in internal energy, enthalpy, and specific entropy for this process.
