NEET Physics Bernoulli's Principle MCQ Question
Which of the following combinations correctly describe Bernoulli's Principle in relation to fluid flow?
The pressure in a fluid decreases as the fluid's velocity increases. 2. Bernoulli's Principle applies only to incompressible fluids in steady flow.
Bernoulli's Principle is only valid for turbulent flow. 2. The total mechanical energy along a streamline remains constant.
An increase in fluid height results in an increase in pressure. 2. Bernoulli's Principle is applicable in both compressible and incompressible fluids.
Fluid velocity remains constant in a pipe of varying cross-section. 2. Pressure differences in a fluid are responsible for changes in flow velocity.
Correct Answer
Detailed Explanation
According to Bernoulli's Principle, for an incompressible fluid in steady flow, an increase in fluid velocity results in a decrease in pressure. This relationship is derived from the conservation of energy in fluid dynamics.
