LAMINAR FLOW . V.S. TURBULENT FLOW. This shows turbulence because it’s all over the place and rough. This part of the picture shows Laminar Flow because it runs very smoothly. In laminar flow, the fluid moves smoothly in orderly layers, with little or no mixing of the fluid across the flow stream. . With laminar flow, there can still exist changes in velocity as the friction of the wall slows the layers closest to the wall, while the flow in the centre of the pipe moves at a faster pace. .
