Hot gases are generated at a temperature of 2100 K and a pressure of 14 MPa in a rocket chamber. The hot gases are expanded ideally to the ambient pressure of 0.1 MPa in a convergent-divergent nozzle having a throat area of 0.1 m2. The molecular mass of the gas is 22 kg/kmol. The ratio of specific heats (γ) of the gas is 1.32. The value of the universal gas constant (Ro) is 8314 J/kmol-K. The acceleration due to gravity, g, is 9.8 m/s2. The specific impulse of the rocket is _______ seconds. (round off to two decimal places)
Correct : 216 to 220
