Carbon dioxide enters an adiabatic nozzle at 1200 K with a velocity of 50 m/s and leaves at 400 K. Assuming constant specific heats at room temperature, determine the Mach number (i) at the inlet and (ii) at the exit of the nozzle. For carbon dioxide Cp = 0.8439kJ/kgK γ = 1.288 Gas constant R = 0.1889kJ/kgK
