Methylethylaldehyde posted:The water hammer in your pipes is water moving at entire meters per second, with a pressure differential of maybe 15 psi, and it'll rattle the pipes pretty good. That little window got water hammered with water going substantial fractions of the speed of sound, with a pressure differential of 3000+ PSI. A literal bomb going off inside would probably cause less overall damage to that window. This is two pages ago, but I thought someone did the math and the water would have been moving at mach 2. I could be misremembering. A mach 2 wall of water is effectively like just getting smooshed between two rocks. The end pieces are in pretty decent shape because they weren't the point of failure, and would have just been sucked in during the collapse.

I had a home OSHA story happen to me on Saturday. I was cleaning the bathroom floor where I keep my cat's litter boxes with bleach and their happened to be a spot of dried cat urine that I didn't see before I put down the bleach. I heard this fizzing sound and immediately backed out of the bathroom closet because I felt my eyes burning. I created chlorinated gas with cat piss and bleach by accident. Cat piss is extremely concentrated with ammonia, I've learned.

There are plenty of alternatives out there.

The water moves so fast it acts like a piston in a diesel engine, crushing and igniting anything organic in 0.9ms. They turned to ash and electrolytes.

I would think that even if the air temperature in the collapsing sub gets super duper high for a few milliseconds that's not enough time to burn a human body much before it gets immersed in seawater.

Phanatic posted:The Juicero was radically overbuilt and literally no expense was spared on making it as unnecessarily high-quality as they could. It did something *dumb*, but it did it very well and the components inside it were top-notch. Yeah, the whole thing with the Juicero was that they had engineered this incredibly expensive ultra-durable precision-crafted press made of high-quality parts machined to impressively tight specifications… in order to press juice packets that you could literally just squeeze out with your hands almost as quickly. The build quality was great, just in service of a completely unnecessary function.

If I remember right, a hand squeeze actually got more out of the packets since the Juicero left some of the contents behind.

The Juicero was for some reason designed to apply uniform pressure to the entire juice packet at once, which was one reason it was so overbuilt (that's a LOT of physical force). Hands, or a smarter mechanism, can focus on the parts of the packet with juice remaining

it's probably because the founder of the company was one of those raw food nutjobs who believed that all the nutrients in food disappear if you heat it or grind it etc. pressing the fruit flat using no mechanical advantage is the only authentic healthy way of doing it

Yeah it was definitely because they thought evenly pressing it was better for the juice. I think the odd part is they had to chunk most fruits to fit them in the pouch but I guess because it's done under their careful eyes it doesn't count.

The fruit in the packets was generally rejected fruit that doesn't end up on grocery shelves because it looks lovely. That's where the money was - the recurring package revenue because they were selling people fruit that otherwise would have went in the garbage or into animal feed. The problem is they had to overprice them to subsidize the cost of the juicer, and it didn't make practical sense at that point. If they had a $100 juicer with a $10/week juice package subscription, they probably would be in business today. Instead they had a juicer that cost $700/per that they sold at cost initially and then at a loss while selling reject fruit and veg for $8/package.

Most of us are perfectly capable of chowing down on a raw apple, a banana, a pineapple, etc. and there actually will be more nutrients for us if we don't boil it first. Vegetables, of course, are another realm(you probably shouldn't try to eat an uncooked potato) where a lot of stuff does need cooking and it goes without saying that raw meats are the realm of madmen.

Even if it reacted infinitely fast, there's not enough oxygen to completely oxidize 300~400kg of meat to CO2+etc. There's inevitably gonna be some chunky leftovers.

the panacea posted:I assume there are multiple insurance companies and a flock of attorneys eagerly awaiting their turn to inspect the wreckage to deny any claims by OceanGate and to establish criminal and civil charges. I don’t know the specific policies held by the examples of physics, but life insurance policies still pay out on suicides. The policy may require it be held a certain amount of time for it to payout, but I’m not sure people getting a policy and immediately committing suicide is actually something that happens with any regularity. And is a submersible without any certification getting any sort of insurance? I guess a company could be like sure we’ll insure your death trap, but when it comes time for payouts we’ll be asking for certifications it can operate at the depths it was attempting to operate at.

Nothing is truly uninsurable. There are insurance companies out there (Lloyd's of London, for instance) who will write you a policy for anything you desire. Want insurance for your all-pufferfish restaurant, your helicopter volcano tour, your uncertified submarine? No problem. They'll have their actuaries do the research and come up with a figure for you to pay. Good luck shopping around.

They'll have their actuaries do the research and come up with a figure for you to pay. Good luck shopping around. Back in 2011 I was part of an organization that was trying to figure out event insurance for our regional burn (aka: small local version of Burning Man) in Texas. That year the state was undergoing a historic drought and was under constant burn-bans and red-flag warnings. There had been major, ruinous wildfires rampaging through the state. So an event that was out in the woods and entirely centered around burning a massive wooden sculpture had an extremely hard time finding insurance coverage. We did finally approach Lloyd's of London, though we didn't go with them in the end. (I believe their quote was loving astronomical, and at the last minute we were able to find another insurer.)

Potato Salad posted:Do you need ear pro for work on pressure vessels? Or should you be listening for hissing? However if we want to harp on something unsafe there is no reason not to be wearing a bump cap when working around industrial pipes at human level. Even when we aren't a kawaii klutz even the best industrial trades folks will just routinely knock their head on pipes and instrumentation. Also the source of how you tell if someone actually goes in the field or not because your bump cap will collect scuffs fairly quickly.
