3) Consider a jet engine with air entering the turbine at T4 = 1177 °C and 5 MPa. The pressure ratio in the turbine is w and the exit of
the nozzle is at 100 kPa. a. Using a cold-air-standard, find the temperature at the exit of the turbine b. Using a cold-air-standard, find the air velocity at the exit of the nozzle
