Characteristic Length

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Characteristic length ( \(l\) ) is the scale of a physical system.  The length is used in 2D and 3D systems for Fluid Dynamics and Thermodynamics defining the parameter of the system.

Examples of:

Characteristic Length Formula

\(\large{ l = \frac{ V } { A }  }\)         


\(\large{ A }\) = surface area of the body

\(\large{ l }\) = characteristic length

\(\large{ V }\) = volume of the body
