[PSUBS-MAILIST] CO2 absorbant efficiency



Jon
Am designing my scrubbers & have come up with a discrepancy between
papers on the psub life support page.
Phils paper on life support states on page 6 that you get 4 hours (240 minutes)
per pound of soda lime.
Your scrubber design page puts it at 200 minutes per kg wich is 90 minutes
per pound (sofnalime). In other words Phils scrubber lasts about 2&1/2 times longer.
This is quite a differance if you are considering taking down enough absorbant for 3 days.
Also ( nit picking now ) Phils paper states Nasa aborts missions at 3%
CO2 levels, while yours states 2%.
