Hi All,
I know escaping from a sub has been discussed
before, but has anybody crunched
the numbers to see if it's possible from a depth
of say 200ft in a K250 or 350.
How long does it take to fill the hull with the
flood valve? The water would be coming
in at 100 psi but this pressure would diminish
progressively as the hull filled. At 3/4
full it would be 25 psi. At what stage would you
start adding compressed air
to help with the equalization of the hull & how
much air would you need & how fast would
it flow in?
If you filled your ballast tanks with air to try
and escape an entanglement first you might
not have enough left to help equalize the
hull.
When the flood time is known, how saturated with
nitrogen are you & what are your chances
of surviving the bends if you opened the hatch
& went straight up?
If this was pre calculated it might be concluded
that a scuba tank (or 2) was needed & decompression
stops at varying depths & times were
necessary.
I don't know the internal volume of a K250, I think
the flood valve is 2"
Regards Alan
