Bernoulli's TheoremHardQuestion 30998

Question

A pitot tube on an aircraft measures air speed. If indicated air speed doubles, dynamic pressure (½ρv²):
  1. A
    Doubles
  2. B
    Triples
  3. C
    Quadruples
    Correct
  4. D
    Stays same

Correct answer

Quadruples

Explanation

Dynamic pressure ∝ v². Doubling speed quadruples dynamic pressure. This is why aircraft structures face 4× the load at twice the speed.
