scuba

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

<BR>Last but not least a first aid set from a car. And most inportant a

<BR><BR>On the future plan are a complete set from a Ambulance car
including defilibrator, oxygen inhalator, medicine etc. <BR>We get older

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
be<BR>> virtually impossible to extrapolate from the small
model,<BR>> and<BR>> aside from that I think there are other
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>>

all<BR>> If you<BR>> make a scale model of a submarine in
