What is Meant by the Reynolds Number?

In Physics, the Reynolds number (Re) is defined as the dimensionless quantity, which is used to find the flow patterns for the fluids. It is mostly used in fluid mechanics. It determines whether the flow of fluid is laminar or turbulent. If the Reynolds number is less than 2000, then the flow of liquid is laminar. If the Reynolds number is greater than 4000, then the fluid flow is turbulent. The formula to calculate the Reynolds number is
Reynolds Number = Inertial Force/ Viscous Force
It means that Re is the product of velocity, density, length divided by the viscosity coefficient.
