LAMINAR FLOW

A flow in which rapid fluctuations are absent. Laminar flow represents the contrast of turbulent flow. It describes the continuous flow of a fluid over surfaces in a smooth manner, with a constant pressure and velocity. When a fluid flows of horizontal surfaces that remain parallel to each other, the layers of the fluid will slide over each other on the stationary surface. Laminar flow usually occurs in places where the flow channel is small in size and the fluid is moving in a slow pace, with high viscosity.
