Krogh length explained

The Krogh Length,

λ _{K} , is the distance to which nutrients diffuse between capillaries, based on cellular consumption of the nutrients.^{[1] [2]}

It can be described as:

λ _{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.
