In case of isentropic flow, the speed of sound in an ideal gas is proportional to (where, T = absolute temperature) ?
Correct answer: C. √T
- A. 1/√T
- B. 1/T
- C. √T
- D. T
Explanation
The ideal-gas sound-speed relation is a = √(γRT), so with γ and molecular weight fixed, sound speed varies as the square root of absolute temperature.
