Q.

The venturi-meter works on:

  1. A

    Bernoulli's principle

  2. B

    The principle of parallel axes

  3. C

    The principle of perpendicular axes

  4. D

    Huygen's principle

Solution

The venturimeter measures fluid flow rate by relating the pressure difference between a wider and narrower section of a pipe to the corresponding speeds, using Bernoulli's principle (conservation of energy in an ideal incompressible fluid).
