Products of combustion enters the nozzle of a gas turbine at the design conditions of 420 kPa, 1200 K and 200 m/s, and they exit at a pressure of 290 kPa at a rate of 3 kg/s. Take k = 1.34 and cp = 1.16 kJ/kg-k for the combustion products. Assuming an isentropic flow, determine
Whether the nozzle is converging or converging-diverging: (1 if converging, 2 if converging-diverging),
The exit velocity and
The exit area.
