Problem 3: (2 points) Example 5.22 A turbine operating on air has inlet conditions of 10 bar, 750 K, and 200 m/s, while exit con- ditions are 1.25 bar and 40 m/s. The mass-flow rate of air is 1000 kg/h. The flow of air is assumed to be reversible adiabatic. Calculate (a) the temperature of air at exit, and (b) the power output of the turbine. Assume Cp = 1.053 kJ/kg-K and adiabatic index 1.375. =
