In a continuous-operation converging-diverging, the inlet diameter 553 mm, the throat diameter is 390 mm, and the exit section diameter is d. the exit section conditions are M =2.5, T = -10C, P₂ = 0.15 atm. Calculate the exit section diameter, inlet conditions: temperature, pressure, velocity and Mach number, and the temperature at the stagnation point of the model in the exit section.
