In . steady flow. the velocity of the fluid particles at any point is constant as time passes. . Unsteady flow. exists whenever the velocity at a point in the fluid changes as time passes.

The use of a . 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. . © 2012 Project Lead The Way, Inc..
