The venturi-meter works on : Bernoulli's principle, Huygen's principle, parallel axes

The venturi-meter works on :

  1. The principle of perpendicular axes
  2. Huygen’s principle
  3. Bernoulli’s principle
  4. The principle of parallel axes

The correct answer is 3) Bernoulli’s principle. A Venturi Meter operates based on Bernoulli’s principle, which states that the difference in pressure created across an obstacle determines the rate of fluid flow.
