WebFeb 2, 2024 · 1) Fick’s First Law gives rise to the formulae: Diffusion Flux = -P (c 2 -c 1 ), where, P is the permeability, an experimentally determined membrane ‘conductance’ for a given gas at a given temperature c2-c1 is the difference in concentration of the gas across the membrane for the direction of flow from c 1 to c 2 Weba diffusion coefficient D. This version of Fick’s law is rarely used for interpreting simple transport studies. However, when assuming a time-independent linear concentration profile (Equation 3.2.4), Fick’s law becomes more straightforward to use, as we shall see later.
