Laminar flow features

Laminar flow features

• A. Orderly Movement With Uniform Speeds
• B. Turbulent Mixing
• C. Random RBC Spacing
• D. No Flow

Answer: (A)

Laminar flow is smooth, orderly movement where fluid travels in parallel layers with minimal cross-layer mixing. In a vessel, the no-slip condition at the wall makes flow slowest near the edge and fastest at the center, giving a predictable, layered velocity profile. Within each layer, speeds are relatively uniform, and the layers slide past one another without chaotic mixing. This contrasts with turbulent flow, which features eddies and irregular mixing, and with no flow at all. So the description of orderly movement with uniform speeds best captures laminar flow.
