NEET Physics Bernoulli's Principle MCQ Question
Consider a pipe with varying cross-sectional areas and heights, where an incompressible fluid is flowing steadily. At a certain point in the pipe, the cross-sectional area decreases, causing the fluid velocity to increase. According to Bernoulli's Principle, what must happen to the pressure at this point?
The pressure decreases.
The pressure remains constant.
The pressure increases.
The pressure fluctuates randomly.
Correct Answer
Detailed Explanation
According to Bernoulli's Principle, as the velocity of fluid increases due to a decrease in cross-sectional area, the pressure must decrease, as derived from the conservation of energy in steady flow.
