Fick law equation
WebReplacing, the D L into Fick's Law yields the following equation. V'gas = DL * ΔP Rearranging this equation allows for determination of the D L using the experimentally measurable values for V' gas and ΔP of the gas across the pulmonary membrane, as follows: DL = V'gas/ (Palveolar - Pcapillary) Measurement WebCombining the above expression with Fick’s first law, J = −D∂c/ ∂x, we obtain the steady state flux through the membrane, (C A CB) h. KD J = −. In the literature, the combination KD/h is called the permeability or sometimes the permeance of the membrane, and the previous equation is then written as. J = P (C A −CB).
