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
