Fick's law can be used to measure flux (J).
For example when the movement of ions is in a non-equilibrium state, net movement of solute across the membrane.
Equation:
J=P x C
J= Flux (Units= Moles/CM/Second)
P= Permeability (Units= CM/Second)
C= Concentration Gradient for uncharged solute across the membrane (Units= Moles/ CM)
Example:
J= ?
P= 20 moles/cm/second
C= 58 moles/cm
J= 20x58= 1160 moles/cm/second
Therefore flux (J) = 1160 moles/cm/second [1].
