Can You Compress Water With Hydraulic Press Using 2000 Bars / 29 000 psi of Pressure? 

The 5000 bar one will be interesting. Perhaps the compression was not from the water but the seals being flexed out in the bore and groves.

@@RolandElliottFirstG It has to be the water because at least we know that the water took most of the force. And the amount water compresses on given pressure is constant. The rest of the system also flexes some amount. Even the steel cylinder probably flexes some amount with these test but the water has to compress also.

​@@aslijogjaNot gasoline, but a Diesel-Air-Mix. Although it could be extremely dangerous! 🤪🤦‍♂️

@@HydraulicPressChannel Ive been wondering for awhile, but where is your accent from? it sounds northern european, but i cant tell. It sounds really cool, tbh.

@@HydraulicPressChannel No, you need 20.000 bar to compress water by 5%. 5% would hardly be noticeable in your setup. The signifikant factors here are the seals, piston, cylinder and the gasses trapped in the water.

AvE did that a lot in his old videos with his hydraulic pump.

good old days @@spikester

Really good question! First I would like to say that it happens only with gasses but I think liquids usually don't compress so it might be just nobody talks about how they get hotter when compressing :D I have to do some research about this!

Elastic deformation so I'm pretty sure it will stay cold. Unless it change state but there is only one state of liquid water unlike ice.

Water is compressible, but pretty much when doing fluid dynamic calculations its considered incompressible. The reason being is you really need gravity to compress water in on itself, for example the oceans, the pressures at the bottom at significantly higher than at the surface, but the water doesn't have anywhere to go except down towards the center of Earth's gravity. Compressing water using some other method that I can think of is pretty much impossible because it's quickly going to find an escape method, violently.

@@memberwhen22 had to relearn that one during the titan Media coverage. Its 5% compressable.

@@memberwhen22 did you not see the part in the video where they compressed water? lol

The impressive thing is that these things are literally compressing a solid block of iron! Imagine taking a cannon ball and trying to shrink it in all directions with pressure. Now imagine a piece bigger than Jupiter, or even the Sun!

I had the same question ❓

You have shifted a decimal. 46 ppm at 1 bar @ 20C but it isn't linear. Compressibility decreases with increasing pressure and increases with colder temperature, warmer water resists compression more. So it depends on whether the change is isothermal. approx 4.4% volume decrease at 1,000 bar @ 0C 3.8% at 20C approx 7.8% volume decrease at 2,000 bar @ OC, 6.8% at 20C A couple of hundred atmosphere pressure wave is relatively easy to generate which is why water is not suitable as a hydraulic fluid, a 1% volume change in a mass under load is a problem for stability with oscillations etc. I was completely unaware of HPP, so that is a 'learn something new every day' thank you. according to wikipedia, " During pascalization, more than 50,000 pounds per square inch (340 MPa, 3.4 kbar) may be applied for approximately fifteen minutes, leading to the inactivation of yeast, mold, and bacteria." "The treatment occurs at low temperatures and does not include the use of food additives. From 1990, some juices, jellies, and jams have been preserved using pascalization in Japan. The technique is now used there to preserve fish and meats, salad dressing, rice cakes, and yogurts. It preserves fruits, vegetable smoothies and other products such as meat for sale in the UK. An early use of pascalization in the United States was to treat guacamole. It did not change the sauce's taste, texture, or color, but the shelf life of the product increased from three days to 30 days.[5] Some treated foods require cold storage because pascalization cannot destroy all proteins, some of them exhibiting enzymatic activity[13] which affects shelf life.[14] In recent years, HPP has also been used in the processing of raw pet food. Most commercial frozen and freeze-dried raw diets now go through post-packaging HPP treatment to destroy potential bacterial and viral contaminants, with salmonella being one of the major concerns"

Teflon quad seals, hydraulic fluid does not compress

I'm not nearly as qualified as you but my assumption was that they had to be perfectly parallel to go in properly. It looked like many broke before or as it was being pushed into the bore.

Strangely enough, rubber seals don't work at super low vacuum levels either.

@@user-db5qd3wd6z They out gas. Very different phenomenon.

Pressure is pressure no matter if it is positive or negative. @@user-db5qd3wd6z

So like the metal piston ring seals in an engine...

@@JoeJ-8282 Pretty much, just rated for higher and sustained pressure.

I keep reading all these low temperature ways of doing it and in my head hearing the crazy engineer I used to work with talk about another way, liquid water is compressible above 800° C but making a container that can withstand the pressure of the water at those temperatures, and then able to pressurise it further would be insane. According to my old coworker it was experimented with as a way to take large volumes of water into space while taking less space in the payload area, containment turned out to be too heavy though.

@chewbacawookie9696 Look at phase II ice in wikipedia, it will avoid embarrassing yourself with such kind of comments

make ice 9 it will be fine

Hmmm! There's a thought! DO the reverse! Put water in the bottom of the cylinder, put the piston all the way down, and then pull it up to draw a vacuum and see how much ice you get!

@@bwhog most uninteresting proposal ever. making ice in a over complicated under efficient vacuum chamber...boring

If you lower the pressure the ice will be denser, not the other way around.

@@stinkiaapje cheeeezzz at least check the wikipedia bro

Yup. With these kinds of conditions we have to consider the air that naturally is dissolved in the water. That is going to compress before the "incompressible" liquid would. I'd still be inclined to believe water can be compressed with enough pressure, but it would raise temperature. I'd have to look up a phase diagram. I should know this, but all the water I ever have to think about is at physiological temperatures =)

@@kma3647 Water compressibility is approx 0.45% at 100 bar, 7.8% volume decrease at 2,000 bar @ OC, 6.8% at 20C

@@kma3647water can be compressed, simple as that.

Fluids can be compressed, look up coefficient of compressibility of a fluids

@@kma3647 If the air is actually in solution in the liquid, it won't be in the form of gas bubbles which can compress. Air bubbles can completely stop a hydraulic system from working (e.g. hydraulic brakes). Dissolved air does apparently have some effect on the compressibility of water (as does any dissolved substance, according to what i managed to Google) but nothing like the effect actual bubbles have.

I think you need 22k bars for ice vi which would be 11x what he can do with that press

It compresses with any pressure increase, just not enough to measure until the pressure is quite high.

How did it maintain pressure when it obviously leaked ? :D

I can only assume that as the bathysphere was raised to the surface, the internal water and air pressure pressed whatever was loose back into place, sealing the leak. While the water didn't compress, the air in the sphere did and that compressed air forced the water out when the bolt was removed. Beebe recounted that that water stream coming out looked like it had steam coming out of it.

If the bathysphere was just 120 mm in diameter, how could it fit a hatch with heavy bolts and windows? And it was supposed to be manned? Damn those freedom units are dumb...

I can prove it at the beamline P61B at the Deutsches Elektronen-Synchrotron using in situ x-ray diffraction.

that's 435,000 psi. steel will flow at that pressure so sounds very difficult . he only did 2000 bars so you want 15 times that .

@@ronblack7870 Yes it is a challenge. Generating that pressure is not difficult by itself (diamond pressing tools can create much higher pressures even if its only on a tiny area for example). The challenge will just be to build something that can actually contain the fluid at that pressure. There is no doubt that it will only be a tiny amount of fluid. But i think it might be interesting.

Or try pouring water into a cavity in a really thick piece of steel, welding or sealing the hole shut and freezing it. See what happens if ice can't expand, or what ice can destroy if it can!

Good up keep work

I thought this also while filming :D I am going to build larger safety box and definetly test this one :D

The water cylinder can't explode I have calculated that it would take 4 times more pressure than we are using here and the hydraulic press itself has also pressure valve to stop it from exploding

You can’t just buy plutonium. If he tried that, he’d get arrested.

No, not due to air or dissolved oxygen. All things are compressible. Gases are highly compressible, liquids moderately so, solids very slightly. Water is about 100 times more compressible than steel, gases (at ordinary atmospheric pressure) about 20,000 times more compressible than water (if I haven't cocked up my guesstimate). So for most applications it's convenient to assume that liquids are incompressible. If you get air bubbles in a hydraulic system (e.g. a brake line) it can completely ruin the functioning of that system just because the bubbles compress so easily. When you bend a steel bar elastically, the inner side of the bend is compressing slightly. A coil spring just makes use of that property in a more useful shape.

@@cr10001 thanks for the information mate , makes sense to me , cheers 🍻

I am not sure, I have to try. I also realized that I can make EXTREME soda by forcing the co2 in with 300 bars on deep sea chamber :D

@@HydraulicPressChannel a sudden pressure release with carbonated water could be quite spectacular to watch, and quite messy :)

Once the CO₂ is fully dissolved everything behaves pretty much like pure water

It's not actually anymore complicated than real hydraulic component to achieve the same end result :D The things that raise the pressure (don't know the official term, is intensifier?) works usually with piston pump using two different sized pistons.

I would hazard a guess with a pipe that large in diameter the actual pressure wasn't that high (compared to what is in the video) maybe 100-300 psi. But the force on the cap would be immense given the surface area. So probably more likely it was some object hitting them.

Sponge Bob flat pants...

James Cameron's watch went there and came back. Under full pressure. Rolex sponsored his expedition, so he has a "cute" little scene where he is checking his watch (attached to the outside robot arm) while he is down there.

If you used those materials to make the cast and plunger…is what I’m asking? Can it be done?

I think they would be pretty close to the water since there is very little of other molecules on those all

@@HydraulicPressChannel soda will be different because it contains carbon dioxide gas
