There are two important special cases of flows, namely laminar and turbulent flows, respectively. The movie shows the velocity profile for laminar flow between two plates. In laminar flow, there is no mixing of the layers of the fluid. Streamlines keep nice and tidy.

If the fluid flows slowly, the flow is usually laminar. A value of a combination of characteristic values of the flow—called the Reynolds number—tells us if a flow is laminar or turbulent.
