Question

Explain different types of flow regimes.

Answer 1

Flow Regimes

For low Reynolds numbers the behavior of a fluid depends mostly on its viscosity and the flow is steady, smooth, viscous, or laminar and n = 1.

For high Reynolds numbers the momentum of the fluid determines its behavior more than the viscosity and the flow is unsteady, churning, roiling, or turbulent and n = 2.

For intermediate Reynolds numbers the flow is transitional — partly laminar and partly turbulent.
