A rocket operates at an absolute chamber pressure of 20 bar to produce thrust, F1. The hot exhaust is optimally expanded to 1 bar (absolute pressure) using a convergent-divergent nozzle with exit to throat area ratio (Ae/At) of 3.5 and thrust coefficient, CF,1 = 1.42.
The same rocket when operated at an absolute chamber pressure of 50 bar produces thrust F2 and the thrust coefficient is CF,2.
Which of the following statement(s) is/are correct?
