Topic: Sub lost visiting the Titanic.

The bottom of the ocean floor ?

Yea that's where they would have ultimately ended up if they descended to depths below the limit of the vessel.

Rip , the 5 explorers.

It’s pretty flat there. That’s it. Would have to move many, many miles to start getting any deeper. Sounds like it’s been found 200m from the titanics bow. No suggestion it hit or touch the ship itself.

Pretty clear it was a catastrophic failure and implosion as the reached the wreck. That’s consistent with the loss of contact. Small mercies that it will have been instantaneous death.

Would the escaping air have been enough to send it that far from the wreck ?  The deaths would've been pretty instantaneous but the build up would've been terrifying.

There’s shelves that go on for 100 and 100s of miles. The titanic is at the bottom of that area, they couldn’t go any deeper unless they moved 100s of miles. This vessel had been down to this depth before. There’s been many concerns that it’s a botch job vessel. This was a dive too many it seems. RIP

I don’t think there would be any escaping air. As soon as there was any sort of weakness it would be an instantaneous implosion. The pressure is that high.

It had no limit because nobody worth their salt was willing to certify it, that's why I have no sympathy for any of them other than the young lad, he would've trusted his dads word.

End of the day, every person in that tube had the finances to buy themselves a brand new sub, they would even have bought one that could take them to the deepest depths, only they know why they didn't.

I get that but the air & pressure difference doesn't just disappear, just wondering is all.

That's pretty much it, isn't it.

I expect the air would be instantly compressed to a tiny fraction of its usual volume. It may even become liquid at that pressure. There's not going to be some kind of jet of air. (Or, at least, that's my guess).

So my balloon experiment was a waste of time.

Pretty good explanation of what probably happened..

Yep, that’s what got me…..crackers

I’m glad it wasn’t the nightmare scenario of it being perfectly intact and those on board slowly suffocating in the abyss.

Hopefully it was all so quick that nobody knew a thing about it.

There are loads of great animal names in there that I had never heard of but I think Headless Chicken Fish has to be my favourite.

I think there's one of them in Liverpool Museum?

You should try playing Subnautica sometime. Bags of fun lol

Unregulated and nothing to say any sea worthiness.

Madness and if this was implosion very little chance of recovering any bodies.

RIP

Just look at it!

Definitely an Everton season ticket holder.

Funnily enough it does look a bit like an Angry Bird.

small enypniastes are a bright pink, and larger individuals are a more reddish-

Too much reddish in it for it to be an Ev fan.

Sad loss of life, glad none of the rescue workers were injured too. Who pays for the rescue operation? Insurance I assume.

I expect the air would be instantly compressed to a tiny fraction of its usual volume. It may even become liquid at that pressure. There's not going to be some kind of jet of air. (Or, at least, that's my guess).

Boyle's Law: P₁V₁ = P₂V₂

Assume that the sub interior is pressurised at the surface pressure, P₁ = 1 atm.
Assume that the sub interior measures 6.5m long with 2.4m diameter, V₁= πr²h = π·1.2² x 6.5 ≈ 29.4m³

At 4000m below sea level, P₂ ≈ 400 atm

Solving for V₂ (the volume of the air in the cabin after catastrophic implosion):
V₂ = (1 x 29.4) / 400 = 0.0735m³ = 73.5 litres (the capacity of a small fridge)

Edit: I used the submersible outside dimensions because I don't have the inside dimensions so the real final volume would be a bit less than that.

Edit 2: I fucked up and used the wrong value for P₂ in the equation, even after putting the right value in the previous line.

You’d get huge rapid heating too, just like a collapsing bubble

A bird down to over 200m. That’s fucking nuts.

Can’t believe the Elephant seal too.

Solving for V₂ (the volume of the air in the cabin after catastrophic implosion):

I bet your a blast at parties Phil?
 

How come you've cancelled out the temperatures which would change significantly at the depths being quoted?

Who would underwrite a Sub that hasn't been able to get certification ?

What?? It wasn't insured either? Wow, mind boggling.

Ok, so I had a pop

PV =nRT. Assume T /293K

100000 x29.4/8.314*293


1206 moles of gas

Now at 4km below the sea, P is about 40334287Pa

So assume temperature is around freezing

V=nRT/P

1206 *8.314*273 /40334287

0.068m3!

However, this is well over the pressure at which air will liquify, so it’s just going to be much less in reality
