Just for fun Titanic calculations

[miketsp]

Its actually worse than that, you wouldn't get any breaths. At that depth the ambient pressure is much higher than the pressure inside of a filled scuba tank! If you opened the valve, gas wouldn't come out of the tank, water would go in!

6000psi is a fairly common industrial pressure.
But as I said at a couple of breaths per cylinder............forget it.

If we want out of the box thinkers, why not just use something that already enables humans to travel to that depth...A SUBMARINE!!!"

I think I have heard of that.....isn't that like a dry suit with a propellor or something?

Wouldn't that defeat the purpose of going diving? They went down in a sub to film it no? Plus Jacque Piccard made a sub dive to the Mariana Trench, which is significantly deeper than the Titanic.

Bearing in mind this is all hypothetical, it would be one mad dive

How about a freedive?

How about a freedive?

Now you're talking my language! Let's see, going to 2.5 miles....I'll need to allow at least 2 weeks for my breathe up, some serious thermal protection......ok let me think on this for a bit!

Sled assisted or not?

Hmm, speaking of the Marianas Trench.....at the deepest point:

1097.73ATA
Best mix is .13% O2 for 1.4ppo2
With air you would have a PPO2 of 230.52
Ambient pressure is 19100.502 psi.

Wow.

If we are takeing it out side the box why don't we use a SUBMARINE as a tank it is neutral or can be made so could hold the gas needed and I am sure we could put a good apeks reg on for the cold water.

 

[teknitroxdiver]

Erm....subs are designed not to IMPLODE. They aren't designed to hold pressure above ambient, they're designed to keep pressure out.

Although that would be an interesting eBay listing...."Submarine, used once, comes with FREE DIN/K valve installed! Buy now and $AVE!"

The answer is obvious. Send the compressor down with the tanks, and fill the cylinders at the bottom. Get 300 bar above ambient pressure, and do a normal dive.

Of course, you need a pretty rigid hose going up from the compressor to the surface to collect the air....
