  • The term "cavitation" already heard, but no idea what could it be?
    How cavitation forms and which consequences are to expect?
    This E-Learning video answers these questions in a understandable form!
    Have fun!
    chapters:
    00:22 - What is cavitation?
    00:39 - Phase diagram
    01:54 - Reasons for cavitation
    02:14 - Why pressure becomes very low?
    02:57 - Piping systems
    06:19 - Collapse of cavitation bubbles in slow motion
    06:57 - Details of cavitation bubbles
    07:44 - Consequences of collapse
    08:24 - Damaged surfaces

      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 CZcams, VHS or any other medium, short, perfect illustrations, information reinforced several times, wow!!!!

      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.

  • @zainahmed1994
    @zainahmed1994 Před 7 lety +14

    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
      @rich1051414 Před 6 lety

      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.

  • @163reasonswhyrealestateage4

  • @contessa.adella
    @contessa.adella Před 4 lety +5

    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.

    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.
