Question

Bernoulli's principle is applicable for:

• A. Non-compressible non-viscous fluid having stream line flow
• B. Non-compressible non-viscous fluid having turbulent flow
• C. Compressible non-viscous fluid having stream line flow
• D. Compressible viscous fluid having stream line flow

Hint:

Bernoulli's principle applies only to non-compressible, non-viscous fluids in streamline flow, not to turbulent flow.

Answer 1

The Correct Option is A

Bernoulli's principle applies to non-compressible, non-viscous fluids that flow in a streamline manner. This means the fluid must have steady, laminar flow without turbulence. The principle cannot be applied to turbulent flow, which is chaotic and irregular. Step 1: Understand Bernoulli's principle.
Bernoulli's equation is based on the assumption of streamline flow, where the flow velocity and pressure are related along the streamline. It assumes that the fluid is incompressible and non-viscous.
Step 2: Streamline vs Turbulent Flow.
Streamline flow is characterized by smooth, parallel layers of fluid. In contrast, turbulent flow is irregular and has eddies or swirls, which violate the assumptions required for Bernoulli's principle.
Step 3: Conclusion.
Therefore, Bernoulli's principle is applicable to non-compressible, non-viscous fluids with streamline flow, which corresponds to option (A).
Final Answer: (A) Non-compressible non-viscous fluid having stream line flow
