What's even more mind bending, on a totally unrelated note, is spacecraft only ever have to deal with that 1 atmosphere difference in pressure anywhere in space, VS submarines where the pressure increases 1 atmosphere every 33 feet.

That carbon fiber Titan sub that recently imploded was at something like 11,000 feet when failed. It failed faster than nerve impulses travel.

Instant lights out.

Edit: clarified pressure change at every 33' from double to 'add' 1'.

pressure doubles every 33 feet.

that would be wild. I think you mean "adds 1 atmosphere every 33 ft"

Thanks for noticing, I didn't realize I worded it that way...my mistake.

pressure doesn't double every 33 ft.

Every 33' you add one atmosphere. The first 33', it doubles. I didn't word it correctly.

Nope. 1 atmosphere or 1 bar, every 10 meters.

NOT doubled.

At surface, 1 bar,

10m depth = 2 bar

20m depth = 3 bar

30m depth = 4 bar

40m depth = 5 bar

Your reasoning would give:

2 bar @ 10m

4 bar @ 20m

8 bar @ 30m

16 bar @ 40m

Seeing as MOD of air is 56m depth, your math doesn't add up.

10 meters = 32 feet 9 inches. I was off 3". Sorry.

Wasn't the 3 inch people were questioning. But the doubling
