The Most Satisfying Laminar Flow Demonstration Ever Made! Laminar flow and turbulent flow are two distinct types of fluid motion that differ in smoothness and predictability. Laminar flow is characterized by smooth, orderly layers of fluid sliding past one another without mixing, with fluid particles following straight, parallel paths called streamlines. This flow pattern typically occurs at low velocities and in fluids with high viscosity, where viscous forces dominate over inertial forces. An
