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.
