NEET Physics Bernoulli's Principle MCQ Question
A fluid flows through a pipe with varying cross-sectional areas at different heights. Which physical quantity remains constant along a streamline according to Bernoulli's principle?
Total mechanical energy per unit volume
Pressure at each point
Velocity of fluid particles
Height of the fluid column
Correct Answer
Detailed Explanation
Bernoulli's principle states that for an incompressible, non-viscous fluid flowing in a streamline, the total mechanical energy per unit volume (sum of pressure energy, kinetic energy, and potential energy) is constant.
