Krogh length

The Krogh Length, $\lambda _{K}$, is the distance to which nutrients diffuse between capillaries, based on cellular consumption of the nutrients.

It can be described as:

$\lambda _{K}={\sqrt {D_{s}c_{o}/R}}$

where $D_{s}$ is the diffusion constant of the solute in the substrate, $c_{o}$ is the concentration in the channel, and $R$ is the consumption by the cells. Units are in terms of length.
