Characteristic Length

Characteristic length ( \(l\) ) is an important dimension that defines the scale of a physical system.  This dimension will vary depending on the system requirements, height of an obstacle, length of the cylinder, etc.

Characteristic Length Formula

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


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

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

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