Quote HistoryQuoted: One of my character shortcomings as a person who likes math and has spent his life reading terribly written hit-pieces about my favorite hobby, is that if you locked me in a room with someone who wrote like that, terrible things would happen. 6,000 psi is not 'two tons'. It's three tons of pressure per square inch. And the 6,000 psi figure isn't even right. It's more like ~5,500 psi. From other Sources - The pressure at the bottom of the Titanic is estimated to be 400 atmospheres – equal to 6000 PSI. Other sources says 5850 psi. I've seen 5,000 PSI and 5,500 PSI. |

Quote HistoryQuoted: We care about them too right? https://www.aljazeera.com/amp/news/2023/6/22/syrians-among-the-hundreds-dead-in-shipwreck-off-coast-of-greece Quote HistoryQuoted: We care about them too right? week after an overloaded boat carrying hundreds of refugees and migrants sank off the western coast of Greece, details of those feared dead are emerging. Most of those on board – estimates range from 400 to 750 – were Pakistanis. Dozens of Egyptians, Syrians and Palestinians also risked their lives for an opportunity to reach Europe on the fishing trawler that departed from Libya. https://www.aljazeera.com/amp/news/2023/6/22/syrians-among-the-hundreds-dead-in-shipwreck-off-coast-of-greece I feel for them as humans. I'm also under no illusion that the people paying to import as many of them as possible into Europe actually give a shit if a boat capsizes every now and then killing a couple hundred....in fact they may view it as a positive thing, let a small number die in order to play on people's sympathies to make it even easier to bring more in. Same for the people getting left to die in the Sonora desert. |

Quote HistoryQuoted: Yeah I haven't gotten a fixed idea on the number of times either. But this is Expedition 5, iirc. And assuming like 12-15 guests per expedition, that means about 5 dives per expedition minimum. Plus some extras along the way, perhaps. I don't think it's only been down like 5 times, but I could be wrong. If "Number of times its been down" = X, then "number of times its come back up" = X-1 |

Quote HistoryQuoted: I know most of us feel bad about 4 people dying in that machine. But is there anyone who feels bad for Cockton Rush(ceo oceangate)? I for one do not. It depends. If the problem was external (ie. tangled in net or debris) and not a result of the way he ran the operation then maybe the only thing he is guilty of is not being more blunt with the paying passengers. The waiver they signed said "you could die" but the waiver you sign to get into six flags or rent a car says the same thing. If it said "this sub does not comply with commonly accepted standards regarding it's design and construction and is considered an experimental design" then I would 100% be on the CEO's side. Put another way, I think his only fault is that he glossed over the risk to paying passengers. Innovation and risk taking is necessary, but the risk must be accepted by the risk takers with full awareness of what the risks are. |

I honestly don't understand why they didn't just make it all out of Stainless Steel or Iron, I mean who Gives a shit how much it weighs. Or even better, why not all out of CF Because carbon fiber's best strength is in the tensile strength of it's fibers. I.E. when they are being pulled apart, NOT when being compressed. Think about it like this... A tire has cords in it to add strength to the rubber. They are arranged so that the pressure inside the tire is pushing against the tensile strength of those cords. This is why tires can hold the high pressures they do. The rubber alone wouldn't be sufficient. Now what happens if you have a higher pressure OUTSIDE the tire than inside? You are now relying on the strength of the rubber and the mass of the cords for the tire to hold it's shape. The tensile strength of the cords is no longer relevant. At all. Whole different ballgame of forces at work here. This is why carbon fiber CAN make very good pressure vessels, but only when the pressure is working against the tensile strength of the fibers (when the pressure is INSIDE the vessel). This is also why carbon fiber is a bad plan for making submarine hulls. Crude explanation I know, but hope it makes sense. |

Quote HistoryQuoted: Quoted: Quoted: Yep People bought into the CEO's bs 90hr media claim. The 96-hour figure was the best available information. It increasingly looks like garbage, but we simply didn't know that at the time - and honestly, we still don't, in any ultimate sense. Nobody has yet to explain where the 96 hour figure came from.

This is coming just from an interview I watched, and obviously doesn't mean that this vessel adhered to the "standard". Average human needs 550 liters per day. So 5 people for 4 days = 11,000 liters A typical oxygen tank (like this) holds 1700 liters and weighs about 10kg  So they would need 7 of those. Of course, this disregards the whole CO2 issue, which is the real limiting factor..... I'm not sure exactly what it would take to scrub that much CO2 for 20 man-days in such a small space... but I'm betting they didn't have it. |

If we are gonna do tourism visits to the wreck of the Titanic why do they not anchor a buoy near it? They could then follow the buoy anchor line down and know that they end up near the wreck. Could even put an automated weather station, wave height reporter, and a navigation beacon on it.

Quote HistoryQuoted: From other Sources - The pressure at the bottom of the Titanic is estimated to be 400 atmospheres – equal to 6000 PSI. Other sources says 5850 psi. I've seen 5,000 PSI and 5,500 PSI. I posted the actual calculations earlier in the thread. Water doesn't really compress (in theory it does, in reality even at 12,500' it does not), so density is pretty constant, at around 64 pounds per cubic foot. That's the figure I used earlier. And even at deep sea pressures it's only going to be a little more than 65 pounds per cubic foot. Let's use 65 as a very reasonable average. Such a cubic foot has 144 inches of footprint, and 65/144 is 0.451388888888 PSI. The titanic sits on the ocean floor at very nearly 12,500 feet. 12,500 * 0.45138888888 gives us ~5642 PSI of pressure. The actual pressure, were you to somehow take a reliable measuring device to the sea floor by the Titanic wreck, would be very, very, very close to this 5642 figure, possibly slightly less, possibly slightly more. The figures of 5000 or 5500 or 5850 or 6000 are not estimates, they are just rounded numbers. Sort of like 'we searched an area about Two Connecticuts in size'. I suppose you could argue that 5500 or 6000 are reasonably 'rounded' figures. The '2' isn't significant. The '40' might not even be significant. But the numbers aren't rounded because of a lack of understanding of how to calculate pressure at depth; they're rounded because they're targeted to an audience who doesn't know, or generally even care, about details. Just throw out a big scary number. *shrug* |

Quote HistoryQuoted: One of my character shortcomings as a person who likes math and has spent his life reading terribly written hit-pieces about my favorite hobby, is that if you locked me in a room with someone who wrote like that, terrible things would happen. 6,000 psi is not 'two tons'. It's three tons of pressure per square inch. And the 6,000 psi figure isn't even right. It's more like ~5,500 psi. Just calculated it right before reading this... 5,568.181818 PSI at 12,500 ft down but what's the difference at that point.

Quote HistoryQuoted: I posted the actual calculations earlier in the thread. Water doesn't really compress (in theory it does, in reality even at 12,500' it does not), so density is pretty constant, at around 64 pounds per cubic foot. That's the figure I used earlier. And even at deep sea pressures it's only going to be a little more than 65 pounds per cubic foot. Let's use 65 as a very reasonable average. Such a cubic foot has 144 inches of footprint, and 65/144 is 0.451388888888 PSI. The titanic sits on the ocean floor at very nearly 12,500 feet. 12,500 * 0.45138888888 gives us ~5642 PSI of pressure.

Quote HistoryQuoted: If we are gonna do tourism visits to the wreck of the Titanic why do they not anchor a buoy near it? They could then follow the buoy anchor line down and know that they end up near the wreck. Could even put an automated weather station, wave height reporter, and a navigation beacon on it. Now you've done it..
