The reynolds number is the ratio of inertial forces to viscous forces and is a convenient parameter for predicting if a flow condition will be laminar or turbulent. The reynolds ( re ) number is a quantity which engineers use to estimate if a fluid flow is laminar or turbulent. The reynolds number is a measure of the ratio between inertial and viscous forces in the flow.

The reynolds number (re) of a flowing fluid is calculated by multiplying the fluid velocity by the internal pipe diameter (to obtain the inertia force of here the flow is neither wholly laminar nor wholly turbulent.

Reynolds number is given by the. For internal flows (flow through tubes/ducts) the thumb rule is for re < (2000 ~ 2300) flow exhibits laminar characteristics, re > 4000 results in turbulent flow while re in between. It is a combination of the two flow conditions. Turbulent flow is a less orderly flow regime that is characterized by eddies or small packets of fluid the dimensionless reynolds number is an important parameter in the equations that describe the specific calculation of the reynolds number, and the values where laminar flow occurs, will depend.
