1 Uniform flow, a flow in which the velocity pattern within a cross-section in the direction of flow does not change from one section to another with distance.
then smooth boundary >100.Roughness in the term of reynolds number Instead of value of is used to classify the type of boundary and limits for these type of flow is <4. then rough boundary . Laminar Flow in a Pipe The behavior of flow in pipes is determined by the Reynolds number Re. .Criterion for Turbulent vs. Flow tends to become turbulent when Re > 3000. the behavior is unpredictable and often switches back and forth between laminar and turbulent.
