The Krogh Length, <math>\lambda_K</math>, is the distance between capillaries at which nutrients diffuse to based on cellular consumption of the nutrients[1][2].
It can be described as:
<math>\lambda_K = \sqrt{D_s c_o/R}</math>
where <math>D_s</math> is the diffusion constant of the solute in the substrate, <math>c_o</math> is the concentration in the channel, and <math>R</math> is the consumption by the cells. Units are in terms of length.
