A dimensionless number is a quantity which describes a
Certain physical system and which is a pure number without
Any physical units
The fluid undergoes irregular fluctuations, or mixing, in
Contrast to laminar flow, in which the fluid moves in smooth
Paths or layers
In turbulent flow the flow the speed of the fluid at a point is continuously undergoing changes in both magnitude and direction
Reynolds number is a dimensionless number that gives a
Measure of the ratio of inertial forces to viscous forces.
Reynolds number is an important parameter in the equations that describe whether flow conditions lead to laminar or turbulent flow
