BACKGROUND
Thrust coefficient or is a dimensionless number that measures the performance of a nozzle, most commonly in a rocket engine, independent of combustion performance. It is often used to compare the performance of different nozzle geometries. After combining it with characteristic velocity , then an effective exhaust velocity and a specific impulse can be found to characterize the overall efficiency of a rocket engine design.
