👉 A ruled fluid, also known as a laminar flow, is a type of fluid motion where the fluid flows in parallel layers or streams without mixing or turbulence. These layers move smoothly past one another, maintaining a distinct boundary between them. This type of flow is characterized by a low Reynolds number, indicating that viscous forces dominate over inertial forces. Ruled fluids are commonly observed in situations involving slow-moving liquids or gases, such as water flowing through a narrow pipe or air moving over a smooth surface, where the fluid's behavior can be precisely predicted and analyzed using mathematical models.
