Why wouldn't a 30ft long snorkel work?
- Thread starter Calvin.
- Start date
i saw something on tv once about something like this, about air pressure.
Some guys went down in a sub marine, with a pressure chamber in it. Then they taped one of the guys' mouth and nose with ductape and pushed him out of the sub. He started swimming towards the surface, but his lungs exploded on the way up cause of the pressure building up.
would this be possible?

Boyle's Law:
P1*V1=P2*V2
If you are at say, 50 feet down and the pressure is hypothetically 5 atm, and the volume of your lungs at that pressure is also 5 L.
If he goes to the surface, where the pressure is 1 atm, you get the following:
(5 atm)*(5 L) = (1 atm)*(X L)
X=25 L
His lungs would have expanded to 5 times their initial volume, that is why divers have to be so careful surfacing. If you don't exhale and be very careful your lungs can definitely explode.

awsome thread, good points so far.
you dont have enough tidal volume to move the air through the snorkel, you would need a snorkel has has a volume less than 500cc. the diameter of the tube would have to be 8fr or higher, otherwise the resistance would too great to over come. so therefore, a 30ft tube with a volume less than 500cc would be to small to pass air, and a wider diameter would have a larger volume ... larger than your lung capacity.
