Air enters a well-insulated turbine operating at steady, state with negligible velocity at 4 mpa, 300°c. the air expands to an exit pressure of 100kpa. the exit velocity and temperature are 90 m/s and 100°c, respectively. the diameter of the exit is 0.6 m. determine the power developed by the turbine (in kw). you may assume air behaves like an ideal gas throughout the process
