NEET Physics Bernoulli's Principle MCQ Question
What must change in a fluid flowing through a pipe of varying cross-sectional area, according to Bernoulli's principle?
The velocity of the fluid must change.
The density of the fluid must increase.
The pressure of the fluid must remain constant.
The temperature of the fluid must decrease.
Correct Answer
Detailed Explanation
According to Bernoulli's principle, as a fluid flows through a pipe of varying cross-sectional area, its velocity must change as a consequence of the equation of continuity.
