[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Everyone dies. At least vaporizing yourself in an experimental carbon fiber tube is a pretty unique and interesting way to go. [/quote] Vaporizing? That implies heat. This sub was 10000 ft underwater in near freezing temperatures. Good luck vaporizing anything. You must’ve studied science at trump university. [/quote] The immense pressure of water entering the capsule would pulverize any living matter in the sub. We are talking surface of the sun temps. Gone. Nothing left. Literally E=mC^2[/quote] Maybe a little PV=nRT too. [/quote] A lot of T[/quote] Exponentially increasing V = exponentially increasing T [/quote] Typo: Exponentially increasing [u]P[/u] = exponentially increasing T Followed by... decreasing V = decreasing T [/quote] PV = nRT doesn't describe this problem well since the ending volume would be hard to estimate. It's easier to use the potential energy on the surface of the hull. The surface area of the carbon fiber hull was approximately 66 meters^2, the surface area of a cylinder 3m x 7m. At a depth of 6,000 ft, the pressure on the hull is about 200 bar (one bar for every 10 meters) That's 20 newtons/meter^2, or 1.32e9 newtons of pressure on the carbon fiber hull. Assuming the hull collapses radially at a distance of 1.5m, that's about 2e9 newton meters, aka 2e9 joules. 1 ton of TNT contains roughly 4e9 joules. It's unlikely that the hull collapse was perfect, but the energy of the implosion was the equivalent of detonating hundreds of pounds of TNT. [/quote]
