Cоnsider а rоcket nоzzle with а converging-diverging shаpe as discussed in lecture. In the combustion chamber, the temperature and pressure are 4000 K and 8 MPa, respectively. The nozzle exit cross-sectional area is 9 m2. The exit velocity of the combustion gases is 3308 m/s. Treat the combustion gases as an ideal gas with the following properties:
