  • Types of Viscous Flows :

The viscous flows may be classified into two types depending upon the factor, whether the viscosity is dominating or not.

  • Laminar Flow :

It is the flow in which the viscosity of the fluid is dominating over the inertia forces.

Such a flow, which takes place at very low velocities, is known as a laminar flow.

A laminar flow can be best understood by considering the liquid moves in the form of concentric cylinders sliding within one another. Concentric cylinders are those having the same center but with different diameters.

It is a theoretical flow and does not come in contact with the engineers.

  • Turbulent Flow :

It is a flow in which the inertia forces are dominating over the viscosity.

Such a flow, which takes place at very high velocities, is known as a laminar flow.

Turbulent flow can be best understood by considering concentric cylinders diffuse or mix with each other and the flow is a disturbed one.

It is a practical flow which comes in contact with the engineers.
