The temperature in isentropic flow_______________?
Correct answer: A. Depends on Mach number only
- A. Depends on Mach number only
- B. Does not depend on Mach number
- C. Cannot drop and then increase again downstream
- D. None of these
Explanation
For isentropic flow of an ideal gas, the static-temperature relation is T/T₀ = 1/[1 + (γ−1)M²/2], so temperature is linked to Mach number when stagnation conditions are fixed. Thus the expected choice is that it depends on Mach number.
