[30 pts] A rocket engine sketched above is being tested on the ground. Liquid hydrogen and oxygen are burned in the combustion chamber producing a combustion gas pressure $p_o = 30$ atm and temperature $T_o = 3500$ K, respectively. The area of the rocket nozzle throat is $A_t = 0.4 \text{m}^2$. The area of the exit is designed so that the exit pressure exactly matches the ambient pressure at a standard altitude of 20 km, $p_a = 5.5293 \times 10^3 \text{Pa}$, and this ambient pressure is maintained in the ground test facility. Assume an isentropic flow through the rocket engine nozzle with an effective value of the ratio of specific heats $\gamma = 1.22$ and a constant value of the specific gas constant $R = 520 \text{J/(kg\cdot K)}$. (a) Calculate the thrust of the rocket engine as measured in the test facility. (b) Calculate the area of the nozzle exit. (c) To test the rocket engine performance at low altitude, the ambient pressure is increased. What is the minimum ambient pressure above which a normal shock would appear in the nozzle?
