Ken, Kurt et al:
We have to consider the area, (in square inches) of the person exiting through the Upper Conning Tower hatch. It doesn't take a lot of air pressure to pop him out through this hole in the pressure hull, which I believe to be about 24" in diameter.
For example, it takes a mere 14psi of pressure (air or nitrogen) to lift a 32-foot long, 54" diameter, 35,700# Polaris A-3 missiile off its seat, on a Lafayette-class boomer, with the muzzle hatch shut. (When that happens, it's a bad day for all) :-))
The bore of the torpedo tubes was generally 53cm and I don't believe
that the plate/piston travelled the full length of the tube. Determining the exact travel is necessary for this calculation, I would imagine.
