Reynolds number indicates the flow of fluid; for a Reynolds number less than 2000, fluid is said to be in laminar flow. For greater than 4000, fluid is said to be in a turbulent flow.

Reynolds number for laminar flow:
Laminar flow occurs at low Reynolds numbers, typically below 2000. Reynolds number is a dimensionless quantity that characterizes the flow regime of a fluid. It is defined as the ratio of inertial forces to viscous forces within the fluid. In the case of laminar flow, viscous forces dominate over inertial forces, leading to smooth and predictable flow patterns.
Explanation:
- For laminar flow, the Reynolds number is less than 2000.
- At low Reynolds numbers, the flow is characterized by smooth, orderly movement of fluid particles.
- Laminar flow is often observed in situations where the fluid velocity is low, and the viscosity of the fluid is high.
- When the Reynolds number exceeds 2000, the flow transitions to turbulent flow, characterized by chaotic and unpredictable motion of fluid particles.
In conclusion, the Reynolds number for laminar flow is typically less than 2000, indicating the dominance of viscous forces over inertial forces in the fluid flow.
