The carburettor of a car is an application of_______________?
Correct answer: C. Both A and B
- A. Venturi meter
- B. Bernoulli equation
- C. Both A and B
- D. None
Explanation
A carburettor uses a narrow Venturi passage to increase air speed; Bernoulli's equation then explains the accompanying pressure decrease that draws fuel into the airflow. Thus both the Venturi arrangement and Bernoulli principle are involved, while choosing only one omits part of the operation.

About Bernoulli's Equation
Bernoulli’s equation applies conservation of energy to steady flow of an incompressible, non-viscous fluid along a streamline: pressure, kinetic and gravitational terms have a constant total. It explains pressure-speed changes in narrow pipes, Venturi meters and lift, and differs from continuity because it relates pressure as well as velocity and height.
