What type of fluid motion is characterized by smooth flow in parallel layers with no mixing?

Laminar flow is characterized by smooth movement in which fluid travels in parallel layers or streamlines with minimal interaction between them. In this type of flow, each layer of fluid moves along its own path, leading to a consistent and orderly motion. This contrasts with turbulent flow, where chaotic and irregular motion occurs, resulting in mixing between layers. In laminar flow, the viscosity and low velocity help maintain stability and uniformity, making it essential in applications where precise flow characteristics are necessary, such as in certain types of chemical reactions and fluid transport systems. Understanding this concept is crucial for engineers and scientists as it impacts the design of systems involving fluid dynamics.
