There are 28.32 liters/cu ft.  If you're running 15 lpm on a free flow
mask that would give you 26 minutes with a 13 cu ft tank.  Too small,
definitely.  I think that a 40 would be a good compromise. That would
give you 80 minutes on free flow or signifigantly more on a demand
valve application.

The composite tanks would be virtually useless since the most common
pressure to pump O2 is around 2200 psi.  Hey, a good use for the old
lp steels!!!
