This is how I want every thing to be explained. Great video

[@energy-tech]

Thank you! We are working on that;)...

[@mountaingrazie3206]

I am engaged in the pump cavitation simulation study, look forward to more exchanges

[@kudzaiwadotiona8792]

excellent!

[@hardcoregaming2090]

me too !

[@mundymorningreport3137]

Delusional science. Fails to explain the plasma spark. Does not detail the actual turbulance of the impellers. Does not mention the fact that the bubbles remain in gas for up to five atmospheres.. Does not explain the diamagnetic properties of the gas; a magnetized impeller would not pit. The obviously whack explanation of the bubble collapse. If the bubble is collapsing from a pressure increase externally driven, it would not collapse from one side. It makes more sense to see that an increase in pressure is causing the bobbles to condense. The collapse happens from the central point of highest pressure. This causes a release of plasma energy delaying the collapse, shaping the torus, disrupting the sphere. The gas has been analyzed. It is made of clumps of water ions and radicals. The gas will dissasemble the atoms of the impellers. You will not find any flake in the fluid. Make a cavitator, collect the gas. It burns like natural gas whit more applications and no pollution.

I'm 45 years old, an engineer (computer systems) and I just now learned that pressure has an effect on the state of a liquid, I definitely was never into materials science or chemistry, but how did I miss this??? Simply put, this is the best learning video I have ever seen, on KZbin, VHS or any other medium, short, perfect illustrations, information reinforced several times, wow!!!!

[@PoorMansChemist]

It's common knowledge. How do you miss a thing like that?

[@dumbotater2158]

Plus, you learned how to pronounce wapor.

[@clarencegreen3071]

A saying by physicists about engineers: "They're so narrow-minded that if you turn them sideways, their minds disappear." Yes, it's a bit arrogant. Engineers might respond, "Physicists are jacks of all trades and masters of none." This is admittedly true, at least at the undergraduate level.

[@PoorMansChemist]

@@clarencegreen3071 You sound like me talking about biologists. Biology, the science that anyone can master if they can memorize things. It doesn't take actual intelligence just a good grasp of mnemonics. 😁😁

[@xmoopx2498]

​@@dumbotater2158lmao that had me fucked up for a minute. I was like wtf is she saying wtf is waper

[@rhinobridge]

I've been studying with youtube videos for years and I have never seen anything like this before! Superb explanation!

[@mountaingrazie3206]

I am engaged in the pump cavitation simulation study, look forward to more exchanges [e-mail]

[@Official_Bengali_Tune]

Yes superb explanation!

[@letsgiveall]

Wonderful presentation. Whoever wrote-directed this video is a brilliant teacher. Thank you for you sharing your time!

[@josemiguelriosperez4587]

I needed a video in order to remember all I have studied in my B.Sc. about cavitation, and this was amazing. Congratulations, and thank you all that have participated in the development of this video!

[@yakupgumustas5229]

I've been supporting my engineering knowledge with a variety of educational KZbin channel since I started college and I have never seen such a extraordinary explanation of a engineering phenomenon. Impeccable!

[@AceSeptre]

Wery good wideo.

[@chrisb4726]

xDDDDDD SO FUNNY. Not.

[@mountaingrazie3206]

I am engaged in the pump cavitation simulation study, look forward to more exchanges

[@ericprobinson]

It is amazing to me that she can see all the other v's correctly but not vapor

[@TiberiusStorm]

Impressive how she was able to pronounce the 'v' in cavitation but not in vapour!

[@aswani4085]

video ki spelling to likna sikh le

[@pratikpatel1784]

This is the best video on the internet regarding the cavitation. thank you - IET

[@AuroraClair]

This video was exactly what I was looking for. Great explanation with real life examples. Thank you very much!

[@jameserayburn]

This is without a doubt one of the best engineering and technology videos I have ever seen. Great job!

[@acenikkoyao1022]

Subscribed! Amazing video! Very comprehensive and easy to understand! Keep up the good job! I really hope you upload English versions of the other videos you uploaded in your E-learning in Thermodynamics and Fluid Dynamics playlists. Such amazingly crafted videos must be shared to the rest of the world! (plus I'm dying to see and learn from those videos myself!) More power to you!

[@yuxiangswjtu]

This video is among the best that explain things with accurate language, great experimental results, vivid simulation and actual samples. Thanks!

[@mehmetturkezer5165]

Simply the best cavitation animation. I have been working on this topic for a while and this video made me understood now very well. Thanks for the effort.

[@163reasonswhyrealestateage4]

This is the most through and fascinating video explanation I have ever seen on cavitation. Thank you for providing an easy to follow format.

[@amizan8653]

Couldn't imagine this topic being explained any more clear. Thank you so much for this video

[@ayushgupta5061]

BY FAR THE BEST VIDEO I HAVE EVER SEEN WHICH EXPLAINED CAVITATION IN MOST AWSOME WAY......THANX AND PLS KEEP UPLOADING SUCH EDUCATIONAL VIDEOS

[@zainahmed1994]

One of the best cavitation videos!! When pressure drops bubbles form when pressure gets back the same bubbles collapse. This collapse of buubles is accompanied by high velocity jets that cause erosion.

[@rich1051414]

Correct. The low pressure in the bubble causes the high pressure water behind it to accelerate through it at high velocity, which cuts the bubble into a donut and gets shot out the other side at extreme speed.

[@contessa.adella]

Wayper pressure! Loved this vid....first time I have seen the bubble collapse in detail and the micro jet it emits....fascinating. Thank you😀 I realise the bubbles forming against a surface can only collapse from the exposed side, so the resulting micro jet must always be directed at that surface. Bubbles collapsing totally surrounded by fluid will jet in random directions.

[@christully1190]

New to the process control industry and this is a great video. Thank you so much for sharing this!

Probably the best video in explaining cavitation..

[@philfrydman2576]

Short & clear technical explanation. Thanks.

[@deepasharma7677]

Great Very clearly explained...your work is appreciated highly

[@tpmvalves5721]

the best explanation of cavitation I ever heard! congrats

[@negarbp1306]

I wish I could learn everything like this. Great video. Thanks a lot for sharing.

[@shruthiramakrishnan3910]

Wonderful video and animation. The concept has been explained with great clarity. Thank you!

[@pruthveshmandle4978]

Best video on cavitation. A tought concept explained with utmost simplicity with animation. Can we just appreciate the real sounds of experimental cavitation bubble implosions attached to the animations? Superb work. Thank you.

[@johnnyrocket4357]

agreed!

[@blancaroca8786]

Excellent and clear. Super attention to images and video demonstrations and slow motion real camera work. So much better educationally than looking for long time at some face talking. A couple of questions: Video says “evaporation” occurs only above 100 C at 1atmos, Maybe shouldn’t we call it “boiling” or “vaporization” to distinguish from evaporation? The latter term evaporation is generally used for what happens well below 100 when your wet clothes dry out for example. Also just to let people know.. boiling needs “prompting” or seed points usually. It is so easy to superheat water in a kitchen microwave making a cup of coffee, throw in a spoon of coffee powder and see instant boil rather than instant coffee and often dangerously ejected. Reason for antibump granules in chemistry when heating liquids in test tubes.

[@riyasv7971]

Well explained, with authentic proof and comprehensive way.. thanks..

[@WantedReward93]

thank you for this wonderful explanation!

[@harshit7123]

perfect! i have seen many videos of fluid but i hv never seen such kind of video. its perfect... thanks for the video

[@nargesnaimi2696]

great video! explained the concept in such an awesome way that no text could do. thank you.

[@laurencium19]

it was 7 years ago and I only watched it today and still amazed by it. I just know cavitation as bubbles formation. This is very helpful on my thesis for kaplan turbine. Thank you!.

[@Limeayy]

wow this is very detailed. Professional AF, i couldn't understand everything but was helpful

[@IzakGt]

I was not directly searching for this but I am really glad I watched it! Great video!

[@grantshort]

IzakGt maybe you are also looking for a source that builds Cavitation Heaters?

[@veronicamonzon1402]

excellent explanation!!!! thank you for sharing

[@smartstudypoint6369]

I'm studying by youtube from last 3 years , but this type of explained (very good than expectation ) video I never watched.. thanks to the team ..

[@vanvo8436]

This video explains really clearly about cavitation I have ever watched. When I was young I watched a video about cavitation bubble occur on blades of the submarine, the noise has exposed the submarine. However, I don't understand clearly until watching this video. Thank you very much.

[@jordanavh]

Great and clear video about cavitation.

[@ashvetmalankar7136]

Excellent explanation! Thank you do much! I hope there will be more videos like this.

[@primaryschoolkids1757]

concept, explanation, graphics and examples. Thumbs up

Can’t be explained better than this ... just awesome

[@aalfazpathan8717]

very nicely explained . Thank you very much for this information.

[@malcolmorrall8338]

Thanks so much for this, great explanation. I’m interested in the geological phenomenon of cavitation in rivers as one way rocks get broken down. Very helpful.

[@kashishmalhotra221]

This is one of the most amazing video for explanation iv'e ever watched. Damn nice

[@Nilanjan35]

All universities should adopt this type of video tutorials for their students.

[@aion2177]

OMG this explanation is the best ive seen. Thank you :)

[@jellybeans8810]

Can't find such Such detailed explanation in my reference book!! Hats off

I wished they explained things like this in Engineering school. The video is detailed and well done.

[@arkadas8196]

Wonderfully presented! Great explanation!! 👏👏

[@lengo9151]

Amazing video . Thanks for sharing knowledge

[@saravanakumar6247]

Really awesome explanation mam I had doubts on cavitation topic for very long time now it has been cleared

[@siva4067]

First class explanation. very impressive presentation

[@michaelgonzales-smith9714]

Agreed, very good video. On a side note, cavitation is f-ing cool. I've know about it for a while but never bothered to the physics of it. Makes total sense. And the shape of the collapsing bubble and the micro jet. I haven't been this excited learning about something like this in a while.

[@arvindpv770]

This is awesome .looking forward for such videos from your team

[@kingofsleightscardmagic1296]

Great visual explanation, thank you!

[@amarraj9557]

Thanks a lot.... for the description. kindly made a video on how to decide whether a substance is pure or not???
