Re: [PSUBS-MAILIST] AIR TIME
Hi Matt,
Not air, oxygen. Submarine life support
systems usually include (at least): a supply of oxygen to replace that which is
consumed; a CO2 scrubber to neutralize Carbon Dioxide we exhale; and a fan to
circulate the air in the cabin. Since oxygen is only about 1/5 of the
atmosphere, you won't need to carry as many tanks as you would if you were using
air.
There have been some good discussions here about
life support in the past. This would be a good topic to research. As
the saying goes: "Give a man a fish and you feed him for a day; teach him to
fish and he'll feed himself for a lifetime" or words to that effect. I
could tell you the answer, but howsabout this: research LIFE SUPPORT in
the Discussion Group Archives, and see if you can determine how much O2 a
person will use in 72 hours. Then you'll have a way of
estimating how much Oxygen your design will require. Let me know how you
do.
VBR,
Pat

Subject: [PSUBS-MAILIST] AIR TIME
A couple of post ago someone was talking about
amount of breathing air ect. Someone mentioned that you had to carry 72
hours of by the Coast Card Rules are you all actually carrying that much air?
and if you are what size tanks and how many of each are you using? The
designs I had in mine were all two person with maximum air capacity of maybe
1hr to 1 1/2hr does this mean I have to incorporate 7 hours of air into my
design?? To me that's a whole lot of air and I have to extend my design out
like 50ft.
