Laminar Vs. Turbulent Flow | Science Trends

Laminar vs. turbulent flow can characterize how fluid is moving, with a laminar flow being a more smooth, orderly flow, and a turbulent flow being rough and chaotic. Laminar flow has a constant velocity at any point within the fluid, imagine similar to a constant flow of traffic. Turbulent flow is chaotic, forms eddies and whirlpools and is similar to the flow of a whitewater rapid.
