NEET 2023, Physics Q22: Hydrodynamic
NEET2023Physics
Q.
The venturi-meter works on:
- A
Bernoulli's principle
- B
The principle of parallel axes
- C
The principle of perpendicular axes
- 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).
