Laminar flow is a type of fluid motion characterized by smooth, parallel layers of fluid that slide past one another without turbulence. It occurs at low velocities and is typically described by a low Reynolds number, indicating a dominance of viscous forces over inertial forces.

Turbulence is the chaotic, unpredictable flow of fluids characterized by vortices, eddies, and rapid changes in pressure and velocity. It plays a critical role in various natural and industrial processes, affecting weather patterns, aircraft performance, and energy efficiency in systems like pipelines and turbines.

Reynolds number is a dimensionless quantity used in fluid mechanics to predict flow patterns in different fluid flow situations, indicating whether the flow will be laminar or turbulent. It is calculated as the ratio of inertial forces to viscous forces and is crucial for understanding and designing systems involving fluid flow, such as pipelines, airfoils, and chemical reactors.

Reynolds number

Viscous forces are internal frictional forces within a fluid that resist the relative motion between different layers of the fluid. These forces are crucial in determining the flow behavior of fluids and are characterized by the fluid's viscosity, which quantifies its resistance to deformation or flow.

Inertial forces, also known as fictitious or pseudo forces, arise in non-inertial reference frames and are perceived when an object is accelerating, such as the sensation of being pushed back in a car as it speeds up. These forces do not result from any physical interaction but are instead a consequence of observing motion from an accelerating frame of reference.
