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.Template:Cn
