[PSUBS-MAILIST] scrubber design

[Alan via Personal_Submersibles]

Another variable in the equation would be performance when the
absorbent was partially used.
If 75% of the absorbent had turned pink (if colour indicating) then
the CO2 would have a shorter dwell time through the remaining active 
absorbent.
 That would also make a mockery of any perfect height to diameter
ratio because it would always be diminishing, wouldn't it?

I went with the computer fan driven scrubbers instead of restoring the original scrubber because the original was very loud.
