<font face="Courier New" size="2">Brian, <br /><br />we have each two cardridge
in the exchange filters for the mask.<br /></font>One is unse in case of
fire
against smoke or in case of battery clorine or other gases.<br />And the
other
cardridge we customize to absorb CO2 in case main LSS filter didnt work
anymore.<br />They are military surplus from Finland and came brandnew for
just
some bucks. <br /><br />During building I have a fire in a bed madraze
becuase of
weölding close by. <br />The smoke fill the compartmnet in seconds with no
view
anymore and nearly unbreathable atmosphere. <br /><br />But we have also a
scuba
automat lifeline system on 6 station on board in case of fire or out of
oxygen
situation. <br />And mobile fire extingusher and a high fog mist fire
fighting
system in each compartment. <br /><br />Also Steinke Hoods, diver suits,
diver scuba
equipment, 1 liferaft, 1 inflate rubber boat,<br />3x 1ts drop weights,
Emergency
oxygen bottles for weeks, emergency CO2 filters (we double it - 4 in
total)
<br />Last but not least a first aid set from a car. And most inportant a
complet
workshop in the engine room. <br />The diver exist room can be use as
rescue
chamber wit a mirror of all systems for air, oxygen, filters on its own.
<br /><br />On the future plan are a complete set from a Ambulance car
including defilibrator, oxygen inhalator, medicine etc. <br />We get older
and on
real offshore operation we are maybe far awawy from other ships and
pepole and
have to fix our problems ourself.. <br /><br />I have a book abouit
emergency
situations on civil submarine from russia. <br />There major accident
clear to
identfy: <br />- Fire on board, <br />- boat catch on the bottom <br />-
diving
with open hatch or launching accident. <br /><br />Deep charges or
torpedos seems not an issue for privat submarines - so we not have
equipment to
prevent that.. <br /><font size="2">(I write this line so I can be sure that
this
email will be stored in a mountain in Montana for ever..)</font>
<br /><br /><font size="2">There are many old submariners and there are many brave

<br />But there are not so much old and brave submariners.. <br />(Okay I
steal this

Drag<br />> results between a model and full scale does not
scale<br />> geometrically. You have to scale model and full
scale off<br />> the dimensionless Reynolds number.
Reynolds number<br />> scaling enables you to scale results between
model and full<br />> scale using either a water tunnel or
air<br />>
tunnel.<br />> Cliff<br />> <br />> <br />> <br />>

<br />> <br />> Hank,<br />> I would
say<br />> no. It would have to be so exact that it would

engineering<br />> principles involved that would come into play ,
Sean would<br />> be the person to ask ! I know that it is
done
in wave<br />> tanks and wind tunnels, but in those you are looking
at<br />> laminar flow and such things, not structural strength
so<br />> much. You might be able to get a rough idea of how
it<br />> would start to collapse maybe. The larger the model
the<br />> better I would think.<br />> <br />> Brian<br />>
