what is reynold's number?
A function to characterize viscous flow around circular cylinder. It is a non-dimensional number expressing the ratio between the inertia force and viscous force. It is defined as:
Re = U.D/v
U = flow velocity
D = cylinder diameter
v = kinematic viscosity of the fluid

Hans:
You are correct describing Reynolds Number as it relates to a cylindrical pipe in a flow field. Reynolds Number does relate viscous effects to inertial effects and can be used to evaluate the nature of the flow fluid over, under, around, or through an object.
For more information about Reynolds Number refer to the Wikipedia link below.
