Physics-Bernoulli's Principle

NEET Physics Bernoulli's Principle MCQ Question

Type: MCQ-conceptual-Hard-Class 11

Which of the following combinations correctly describe Bernoulli's Principle in relation to fluid flow?

A

The pressure in a fluid decreases as the fluid's velocity increases. 2. Bernoulli's Principle applies only to incompressible fluids in steady flow.

B

Bernoulli's Principle is only valid for turbulent flow. 2. The total mechanical energy along a streamline remains constant.

C

An increase in fluid height results in an increase in pressure. 2. Bernoulli's Principle is applicable in both compressible and incompressible fluids.

D

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

Option A

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.
