Problem 55P
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 (a) at the inlet and (b) at the exit of the nozzle. Assess the accuracy of the constant specific heat assumption.

Problem 55P
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 (a) at the inlet and (b) at the exit of the nozzle. Assess the accuracy of the constant specific heat assumption.
ANSWER:
Solution
Step 1
Carbon dioxide enters an adiabatic nozzle at 1200K with a velocity of 50m/s and leaves at 400k is shown below.
The gas constant of carbon dioxide K=0.1889kJ/kgK
Specific heat, Cp =0.8439kJ/kgK
