Krogh Length

The Krogh Length, ${\displaystyle \lambda _{K}}$, is the distance between capillaries at which nutrients diffuse to based on cellular consumption of the nutrients.^[1][2]

It can be described as:

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

where  is the diffusion constant of the solute in the substrate,  is the concentration in the channel, and  is the consumption by the cells. Units are in terms of length.
