Q.47 A rocket operates at an absolute chamber pressure of 20 bar to produce thrust, F1. At The hot exhaust is optimally expanded to 1 bar (absolute pressure) using a convergent-divergent nozzle with exit to throat area ratio (A) of 3.5 and thrust coefficient, C7,1 =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? (A) ( F2 F1 = 2.5 (B) > 2.5 F1 (C) CF,2 CF,1 = 1 (D) CF,2 > 1 CF,1
