| Re: Chemistry of CO2 Neutralisation - Can weight be used as an indicator of scruber l
I am glad to see that input by other people is making the whole thing more interesting. Well mentioned Owen!
Your idea to weight the dried S/L would definitely give more accurate and realistic results as the water factor is eliminated from our equation. However there is one drawback with this method tough. It requires, as you mentioned allready, expended sorb. This experiment is much more expensive to carry out as there will be a lot of wasted sorb.
Also inhaling with the inhalation hose disconnected is not simulating inhaling during a dive as there is always fresh air in the loop. All parameters are then affected.
Nevertheless we can design a parallel experiment to measure water content in the sorb by drying after different breathing times (actual dives) to calculate a blank reference curve. This curve i.e. a function WATER = f(breathing time) would come as a mean value +/- SD and could be used later to estimate +/- the expected water content of the sorb after a given period of time in use. |
