Aerofils are so designed that the speed of air

Options

  1. Aon top side is more than on lower side
  2. Bon top side is less than on lower side
  3. Cis same on both sides
  4. Dis turbulent

Correct answer

A. on top side is more than on lower side

Step-by-step solution

The aerofils are so designed that P_ upper side P_ lower side so that the aerofils get a lifting force in upward direction. According to Bernoulli's theorem, where the pressure is large, the velocity will be minimum or vice-versa. Thus, v_ upper side v_ lower side
