What is laminar and turbulent flow?
Laminar flow is a very well behave flow usually occurring at low speeds for most fluids. In the laminar flow regime it is possible to determine theoretically the speed of any particle between the center of a pipe and the wall. Most fluids have to be carried at a much higher velocity which puts them in the turbulent flow regime. For turbulent flow, the fluid particles move in many directions, each particle reacts with its neighbor in an unpredictable fashion creating much higher internal friction than is present in the laminar flow situation. If you put dye in a laminar flow system, you will observe nice long streams of dye undisturbed by the surrounding liquid. The same dye inserted in a turbulent flow will immediately be dispersed through out the liquid.
