Abstract
We derive a formula for the correlation of the three practical transportparameters Lp, σ, and ω appearing in Kedem-Katchalskyequations. It has a form ω = KLp/vs(1-σ), where K = 0.0306 is a universal constant independent ofthe choice of a membrane and a solute. It can be used to calculate the valueof any of these parameters, provided the other two and the molar volume\(\overline {\upsilon _s } \) of the solute are known. The formula couldbe very useful, in particular when measurements of the parameters aredifficult or even impossible.
