Thermodynamics problem, use Water Property Tables (A4-A6)

An adiabatic gas turbine expands air at 1300 kPa and 500 to 100 kPa and 127. Air enters the turbine through a 0.2 m2 opening with an average velocity of 40 ms, and exhausts through a 1.0 m2 opening. Assuming the potential energy is negligible and the gas constant is = 0.287 kJ(kg K) Tasks: (a) Determine the mass flow rate of air through the turbine (10 pts) (b) Determine the average velocity of air leaving the turbine (5 pts) (c) Determine the power produced by the turbine (10 pts)
