Question

Laminar flow is characterized by:

• A. High Reynolds number
• B. Random particle motion
• C. Smooth, orderly layers
• D. Sudden pressure drops

Hint:

Laminar flow is typically observed at low Reynolds numbers, where the flow is smooth and stable, without turbulence or irregular fluctuations.

Answer 1

The Correct Option is C

Laminar flow is a type of fluid flow in which the fluid flows in smooth, orderly layers with little to no mixing between them. In laminar flow, fluid particles move along well-defined paths or streamlines, and the flow is characterized by a low Reynolds number (Re), typically below 2000. The flow is steady, and there is minimal disruption or turbulence within the fluid.
In contrast, turbulent flow occurs at high Reynolds numbers, where there is chaotic motion, and the flow becomes irregular with eddies and vortices. In laminar flow, there is no random particle motion or sudden pressure drops, and the fluid behaves in a stable, predictable manner.
Hence, the correct answer is: Smooth, orderly layers.
