Air enters a one-inlet, one-exit control volume at 6 bar, 500 K and 30 m/s through a flow area of 28 cm2. At the exit, the pressure is 3 bar, the temperature is 456.5 K, and the velocity is 300 m/s. The air behaves as an ideal gas. For steady-state operation, determine (a) the mass flow rate, in kg/s and (b) the exit area, in cm2.
