Titan Submersible

I ignored it because I've explained the laziness of that type of rhetoric to you before and you just ignored it. No point me banging my head against that brick wall again.

 

Says the person who posted about migrants being put up in hotels…

 

I was replying to the other person who posted about 100s of them dying each day crossing the channel but not getting media time but these billionaires are.

 

If you say so.

That might well be the case but you can’t join in with a political conversation with a political response, then moan about it getting political.

 

Well why reply to my comment to BR? To then not reply then bring up a thread from months ago, strange bloke.

I didn't have anything in particular to say in response to that post. In this thread you said I was ignoring a part of your argument, I said I'd addressed it before, you said "if you say so" as if I was bullshitting, so I provided a link.

Doesn't seem strange to me.

 

Well why jump on the thread with the smart comment of "didn't know it was illegal to cross the border I went on holiday to france" you post something for a reaction when you got it don't reply. Anyway I'm done have a nice day.

 

I think you mean the Med rather than the Channel - although its not quite hundreds per day there was a ship sank the other day with an estimated 500 on it and another 11 drowned when another ship overturned off the coast of Africa yesterday or the day before.

 

Can't see how they'll ever find the sub. It took them 70 years to find the titanic. They are looking for the worlds shortest needle in the worlds biggest haystack. RIP to those on board.

 

That depends on the country. You *do not* need a passport to travel to 4 countries from the UK - Ireland, Isle of Man, Jersey and Guernsey - due to the common travel area. If you are in Schengen, you do not need a passport to travel to any other country in Schengen but an outsider needs a passport to enter Schengen (iirc its the same between the MERCUSOR countries like Argentina and Brazil).

You do need a passport - and sometimes a visa - to travel to any other country. However, anyone - including you - has the right to enter another country by irregular means if you claim asylum within a short time after arrival if that country has signed the Refugee Convention (most have). That country then has to process your application according to their criteria and can accept you as an asylum seeker or reject your claim.

 

Could well have lost pressure and imploded.

 

That's one theory, but surely would have seen some debris by now if that was the case.

 

I think you have misunderstood the concept of submersibles/submarines.

Both internally remain pretty much at surface pressure like commercial aircraft do except they are designed resist external pressure on the hull whilst airliners are designed to resist internal pressure at high altitudes where air pressure is obviously low but cabin pressure is only marginally lower than at ground level . The other major difference is that the pressure on the hull of a submersible a 12500 feet (the Titanic wreck depth) is close to 11 tons per square metre!. At that depth they don't 'leak'. Any failure in hull integrity results in an explosive implosion. The fact they are breathing at pretty much normal pressure means they can surface relatively quickly from any depth without risk of suffering decompression problems* Nevertheless Wreckage from an implosion at that depth would likely never make it to the surface


* A diver not enclosed in a vessel breathes in air (or other gases if below 60 metres) at the same ambient pressure as the surrounding water At 10 meters of depth pressure is double. Obviously the differential diminishes every 10 metres This balance s achieved by the demand valve delivering air at the same ambient pressure to either a fully enclosed face mask or a regulator he has in his mouth. This keeps sinuses lungs ears eyes from rupturing If wearing a dry suit you also have to add air into it to prevent 'suit squeeze' which can be very unpleasant. (I once saw a novice diver who had not been properly instructed and had forgotten to do this and even though he had only gone to about 15 metres when he took his dry suit off he was covered in red weals and bruises)
The big problem is the body absorbs high levels of nitrogen when breathing under pressure and the depth and duration of time spent at that depth affect how much . This necessitates getting rid of that excess by breathing during a slow ascent and in some cases having frequent decompression stops at various depths. Usually you spend several minutes hanging on a shot line at around 10-15 minutes to get rid of any dangerous levels in your bloodstream. The dive planning tells you how long etc and how long before you can dive again Noawadays you use a dive computer that does all the calculations for you before during and after the actual dive. Get it wrong and the nitrogen bubbles form in your bloodsteram (like opening a bottle of fizzy water too fast) and you will almost certainly get Caissons disease ( 'The bends') which can lead to paralysis or death. Most commercial divers on oil rigs etc. have access to a barometric chamber that can simulate pressure at depth so if a diver for example, has to make a rapid ascent he is quickly transferred to the chamber which is pressurised and they then gradually reduce the pressure over several hours to simulate a slow ascent and allow the body to bleed off the excess nitrogen.

 

Could well have lost pressure and filled up wi watter.

 

Err no! See post #96

 

I doubt it. I think if this has happened they'll be lucky to ever find anything.

 

Search expanded to 10k Square miles or ocean really is a needle in a hay stack. I'd imagine the company running these tours are in some serious bother.
