Re: [APD] carbo plus units and kh

The chart is very interesting, but unless someone does some  
calculations, we don't know if that parameter listed for permeability  
means much.  In other words, a reading of 10,000 might be very bad,  
wasting half of the CO2, or it might mean an increase of 1% in CO2  
usage.  Back when I was working, this type of calculation would be a  
piece of cake for me, but today it is more like a granite boulder - I  
try not to chew those.  Who wants to do the calculation and put this  
into context?
