Don't know if this helps...
Gurley numbers are used to indicate the relative permeability of membranes or materials...The number (in sec) is obtained by measuring how long a known volume of air at constant pressure takes to pass through a material.
Your constants would be air Pressure, Area of membrane...
Here is a website you might find interesting...
In the past, I've run across some good literature on this from WL Gore...the manufacturer of GoreTex!!
