An adiabatic gas turbine expands air at 1300 kPa and 500 °C to 100 kPa and 127 °C. Air enters the turbine through a 0.2 m2 opening with an average velocity of 40 m/s, and exhausts through a 1 m2 opening.

a. List all the appropriate assumptions to solve this problem.

b. Determine the specific volumes of both inlet and outlet.

c. Determine the mass flow rate of air through the turbine.

d. Calculate the velocity at the outlet.

e. Calculate the power (kW) produced by the turbine.
