Does nyone have access to details for water permeability of materials used in pipe manufacture?
I am wanting to calculate how much water "soaks through" the pipe surfaces that we have.
I have managed to find and understand the relationship for "concrete", but also need to find the factors applicable for other materials and especially Asbestos Cement.
The equation looks like this
k=(V*T)/(h*A*t) Where
V = volume of water passing
T = material thickness
h = pressure
A = Area exposed to water
t = time of exposure
(units that I'm using are SI, but I'm able to do the conversions if you can tell me the "k" factor and some detail of conditions applicable.)
From the sources I've found for concrete, the values range 1E-11 to 1E-4, and at a pinch, I'll just have to extrapolate AC (Asbestoc Cement) to be somewhere in that range.
Would also be interested in similar factors for other usual pipe materials.
