Alright my dudes, how devastating is 200 bars of uncontrolled pressure. If air or water with such force was to be realised from it's container could it cut a person in half. Also could you tell me where I may find such pressure ?
Pic kind of related.

PCP air rifles are filled to 200 bar with a special pump.

I used to work with 60 bar steam. Shit was fucking scary. So yeh, I reckon 200 would probably cut a person in half or at least blow a hole in them, you would need a large volume and constant flow at that pressure though I reckon. Single hit probably wouldn't be enough.
Water jet cutter would do it like a hot knife through butter.You could also try an industrial pressure cleaner.

What did you do with that steam Anon ?
Those water cutters hit at 1000 bars.

200 bar is very close to the critical point of water. Where water and steam are indistinguishable from each other. You could toss a wrench pass a pinhole leak and it would cut it in half, at least that's what people have told me. Big power generation plants run at 200+bar of steam.

Common rail diesel injection pump will do up to about 2000 bar if you want to go crazy.

You can easily buy 200 bar pressure cleaners so it's probably not inherently crazy dangerous with fluids.

Pressure is a force over an area, releasing pressure the opening size will determine the speed of egress as well. Pressure is only part of it.

It won't be a simple case of releasing it from its container with water. Water is barely compressible, so you're going to have to be pushing it out with some other force.

Not sure about very, and there's a temperature component to consider.

I didn't need this knowledge to build, but this question relates to my job, there was this ridiculously high parameter (200 bars) describing water/ air hose, and I needed some reference point to, kind of, know what it means. And just knowing it's dangerous wasn't satisfying enough. Thanks for your answers anons, much obliged

Yep. Man sized pressure washer or any hydraulic system (diggers, tractors ect)

Its not a big deal when a line goes bang. You want this pressure with much higher flowrate (than 10L/sec) or similar flowrate with much higher pressure if you really want to do some damage

That's 'domestically' available ones. I have a couple of 2500 bar common rails in my garage atm, and a pump that'll go up to >3000.

>>1600966
It's how the pump responds to springing a leak more than anything, so a low flow pump can respond in a very narrow set of circumstances because it can't keep increasing flow as the leak gets bigger. If you have a high flow pump with a controller that causes it to increase flow to maintain pressure you've got a nasty pos on your hands, you can get thick high pressure jets coming out, or slightly less bad a billion little pinholes. If you're doing something like hydroforming with high pressure, springing a leak will cause it to shut down.

On the submarine out in Guam, when shit like that would go down, we had brooms literally only use with high pressure leaks secured for such things. Shit sliced it like a fuckin samurai movie, it just disappears dudes. Please follow the law and be very careful. Get fucking sandbags at least please. And a big red kill switch with you. Dont do it alone. Wish you luck and safety friend. Dont mess with hydraulic fluid, that shit has the diesel effect. It turns into a thick gas and drowns you in painful death. Love you dude be safe.
