Question

There are three ways to treat the chemical composition in a rocket nozzle. Indicate which of the statements below applies to the methods listed to the left by circling the appropriate letter: The chemical composition of the flow is in a state of chemical equilibrium at every point in the expanding nozzle flow. The chemical composition is continually adjusting and must be computed using finite reaction rates throughout the nozzle flow. Chemical equilibrium is attained in the combustion chamber and this composition is invariant throughout the nozzle. The chemical composition at the exit is the same as in the combustion chamber.

Explanation / Answer

Kinetics- b since flow through the nozzle is not costant.

Frozen equilibrium- a since flow is in chemical equilibrium at every point.

Shifting equilibrium- c since there is same chemical composition at the combustion chamber and exit.
