What does the Reynolds number depend on?

The Reynolds number is an important parameter in Transport Phenomena. It is used extensively in many calculations dealing with fluid flow, mass transfer and heat transfer. It is the ratio of the inertial forces to the viscous forces and depends on a characteristic length, velocity, density and viscosity of the fluid.

What does the Reynolds number tell us?

In fluid mechanics, the Reynolds number (Re) is a dimensionless number that gives a measure of the ratio of inertial forces to viscous forces and consequently quantifies the relative importance of these two types of forces for given flow conditions.
