As some have pointed out there is definitely more going on here than just air pressure. In fact you cannot talk about any fluid flow with only talking about pressure. You have to always talk about fluid velocity and pressure together. We do know there is the centrifugal effect of water being thrown out the sides and also down the middle. But the reason there is ever any flow at all is due to pressure differences. The ball is being dragged down by the water but it is also moving fast and so the atmosphere pushes it down as well. There is also rarified air and eater vapor that forms under the ball pushing it up (maybe). This is definitely a phenomenon that I have never seen before in any literature so if anyone has any resources are open to hear more about this.

@Anankin12 5 жыл бұрын

But isn't pressure in a fluid inversely proportional to its velocity? Shouldn't there be more pressure in the centre, where the fluid is at its slowest? A.k.a.: imho, the ball doesn't sink because there is less pressure in the centre rather than on the sides, although that could explain that anyway through a reduction in Archimede's force due to the lowered pressure

@Anankin12 5 жыл бұрын

Also, I don't think atmospheric pressure has anything to do with it, because once it is underwater it can't affect it, but I haven't seen the full video yet. Might cancel the comment. Edit: I was wrong, atmospheric pressure plays a role, but I still don't think it works like you said. When it's completely sunk there is no way for the air to push it down, since it doesn't make any contact with it.

I thought the ball would go down for the same reason your helium balloon goes in front of the car when you drive. eg the water is heavier than the ball and will move toward the wall faster than the ball who get pushed center. With less force pushing the ball upward the ball sink. As for the ball going up I agree with other comments about water vapor since your other videos shows that water boils at that pressure. For the same centropic reason the vapor is also pushed toward the center under the ball.

@mikefochtman7164 4 жыл бұрын

The type of 'spinner' you used has a serious effect on this experiment. The agitator at the bottom, is in effect, a sort of centrifugal pump. Water is constantly being flung outward at the bottom, then forced up the walls of the container and flowing back in toward the center (all with considerable tangential flow as well). (this is why this type of 'mixer' is so often used, it circulates the fluid both tangentially around the container, but also radially outward, upward, and back down in the center) This downflow in the exact center, IMHO, is what drags the ball below the surface. After all, when the ball is completely submerged, the air isn't acting on the ball at all. As others have pointed out, as the water spins around it also has centrifugal forces acting on it, so the surface of the water is always perpendicular to the combined centrifugal/ gravitational forces acting on it. It would be very enlightening to use a different mechanism to 'spin' the water. For example, remove the agitator and spin the entire beaker. With all the water spinning at the same RPM, you would not set up the same internal flow pattern. The water at the bottom would not be 'pushed' outward to the walls of the beaker any more than any other water, so there should not be any 'vertical' circulation. Edit: Without this, I predict the water will form a parabola, but the ball will not be 'sucked/pushed' under the surface (much like you saw it under the high vacuum condition).

@@sangnguyentan1911 I believe he's referring to the shape the water surface would form if you spin the entire beaker as I suggested. Near the very center, with centrifugal force very low and gravity, the shape of the surface would be nearly a flat plane. Only as the radius increases does the centrifugal force become significant and then the surface curves upward. This is exactly how a mirror for a reflector telescope is started. The final shape has to be ground precisely, but the basic concave shape is formed by 'spinning' the glass while still molten.

As has already been pointed out - Water boils under vacuum. The cooler the water is, the lower the atmospheric pressure needs to be to reach the boiling point. With a low enough pressure, tap water will boil at room temperature. Yes, that's a Fact!. If you place the ball on still water and then pull a vacuum, the water will boil all around the ball like a pan of water on the stove, only the water will NOT be hot to the touch. As the air is evacuated from the chamber water will reach a point at which it boils. Right after this, the vacuum gauge will stabilize and stop dropping until all the water is gone, then it will drop to whatever level your pump is capable of pulling on your vacuum chamber. In your experiment, the "air pocket" that formed under the ball while rotating the water is the water's gaseous state trying to reach the surface. This action creates a lifting force. The bubble formes in the middle of the vortex since this is the water's lowest pressure point. Going a little off subject. Something else interesting about water is it has a "triple point". That is the temperature and pressure at which the three phases (gas, liquid, and solid) can coexist in thermodynamic equilibrium. Under the correct circumstances, water can turn directly from ice (a solid) to gas without first becoming a liquid.

In the normal pressure part, is it really the pressure from the air that sinks the ball, or the fact that the moving water is moving faster below the ball than above ? Perhaps the high-pressure experiment will tell. In the low pressure experiment, the air vortex below is likely to be vacuum, and the ball seems to be just floating on the walls of the vortex. These are my hypotheses.

@yangzhou5530 5 жыл бұрын

Agree. The velocity of the water below is faster than that above the ball, producing a downward force due to the pressure difference(in addition to the original pressure difference).

Great experiment! Overall air pressure has no direct effect on the ball - it pushes it down (via water) as much as it pushes it up. But the lower pressure allows building of steam- bubbles. They gather in the middle where the pressure is low and they build eventually a vapor column that wants to go up and pushes up the ball. It would be interesting to see the experiment with slightly warmer or colder water...

i disagree with you conclusion: the ball goes down because of the water flow. when you reduce the pressure you boil the water and the tendency is the densest fluid go outward. this, then, creates a zone with water vapour instead of water, having less thrust downward. think of the stirrer as a pump that sends water from the bottom back to the top and you will understand. when the water vaporizes the pump starts to 'cavitate' and the total flow is reduced. this only happened because the vortex widened at the bottom. with a taller vessel or wider ball or a fluid that wouldnt evaporate at this low pressure (some polimer maybe?) you wouldnt see this effect. a test you can make to prove this is to fill the vessel to the brim with water and seal it. there is no air pressure and the ball will go down because of the 'convectional' water flow. you could even make a hole in the top of the lid and vacuum it and as far as there is no significant amount of water evaporated to start forming a cone the ball will stay down.

@rafaelthetall 5 жыл бұрын

and, watching again i noticed another point: the 'air' beneath the ball is not air but water vapour that accumulated down there because the ball diverts the downward water flow from getting in the center of the spinner. bellow and above the ball where are gases (the 'inner cone') the pressure will be the same (a pressure low enough to evaporate water) . in the wet part of the ball are where the forces happens: buoyance and drag find equilibrium with that 'amount' of ball. the cone does not form by air pressure. it forms by inertia of the fluid climbing up the walls by the "velocity/energy" imparted unto it by the impeller, centrifuge forces and all that. by making the vessel closed at the top and filled to the brim you prove that: the water returns to the top and fills back the conical cavity without having the chance to climb. to see the flow you could add some purpurin or other solid particles.

Great experiment! I think the explanation needs some work, though. If it's just the air pressure pushing the ball down, then how does the ball "know" about the air pressure when it is already underwater? The only way the air pressure should be able to "communicate" downward through the water is by changing the pressure at the surface, which would only increase the total pressure at every point below globally. For the ball to be pushed downward all the way, there would have to be a gradient in pressure decreasing from top to bottom, a reverse of the gradient that would be there from gravity alone (when there's no vortex). So I think Joël Séguin's hypothesis is more likely - that air resistance friction slows down the vortex at the top, and those layers of slowed-down spinning water slow down the lower layers a bit less, creating a gradient in speed from top to bottom enough to allow Bernoulli's principle to reverse the gradient in pressure that the water would have from gravity alone. The air pressure would then only provide the initial push down, with the friction-slowdown gradient pushing the rest of the way.

@TheActionLab 5 жыл бұрын

Well I showed in a previous video that the pressure propagated through the water so it doesn’t matter whether something is underwater or not it still feels the lower vacuum. For example if I had a balloon underwater in the vacuum chamber And I lowered the pressure of the balloon with still expand in fact that’s what I did in previous video. There is probably an affect due to the dissolved air or water vapor under the ball also

@davidellsworth4203 5 жыл бұрын

Yes, lowering the air pressure on top of the water should lower the pressure of the water below, but it should do so globally. Thus, a change in air pressure alone should not be enough to make the net force on the ball in this vortex experiment, when it is already underwater, change from upward to downward or vice-versa (i.e. the direction of the pressure gradient should stay the same). Pressure-wise, having air on top should only increase the pressure everywhere below just like having some extra water on top (with vacuum above). And my guess would be that dissolved air should have a negligible effect in this vortex experiment (i.e. not qualitatively change the experiment's result).

@cennofranjo 5 жыл бұрын

@@davidellsworth4203 I agree with you. It's not the air pressure that is pushing the ball downwards underwater. It's the pressure gradient. The same kind of pressure gradient that keeps the ball in the centre. Velocity of water will be higher near the bottom(as the strirer is at the bottom) than at the top surface of water. So pressure will be lower at the bottom. Same way velocity of water is high at the centre(so less pressure) and the ball tries to remain in the center.

Hmmm...I don’t think you can attribute all of the air under the ball to dissolved air. It is not trapped under there like a plug. But I agree that this could be part of the mechanism. There is a lot going on here, there is water dragging the ball down due to no-slip condition at the surface of the ball. There is air/water vapor below the ball as you said probably pushing it up. There is air pressure above pushing the ball down that mostly goes away under vacuum. This is definitely interesting though

I have a hard time believing the air pressure could fully submerge the ball. The water would have to be less dense than the air in the ball. I think it's the water flow. The vacuum allows the water to rise higher on the outside. With more water on the outside and no water in the center, the toroidal flow forcing the ball down is greatly reduced. Not only is the flow reduced, the surface are of the water contact is greatly reduced.

Does the water in the straw rises up because blowing air above creates a low pressure, so the air in the straw goes out and rises the water up ? If yes, then why doesn't the air surrounding the straw replaces the blown air instead of the air inside the straw, just like the effect in the video of the table fan's back. I'd be glad if you'd answer. Not an entire video but just a reply would be more than enough. PS. I still praise the day when I'd found 5his channel 😍. Just a few days to go to finish binge-watching all the videos of AL

uc_human If the idea is true, I think that they both do since there has to be some sort of equilibrium.

Instead of thinking about it like the air in the straw is leaving so it “sucks up” or pulls the water up, its more like the atmospheric pressure on top of the water in the beaker is pushing water down, causing water to go up the straw, like a mercury barometer. Normally pressure above the straw and above the beaker are the same, but when blowing air, the pressure above the straw is lower due to fluid air moving quickly (Bernoulli effect I think) so water is pushed up by the normal pressure air above the beaker

You're blowing the air above the straw away, so it creates a low pressure zone. And water rises to fill it up. Like a burning candle in a jar placed in a bowl of water

As a college graduate in physics from 101-499, I didn't even expect this... I anticipated that no matter how low you drop the atmospheric pressure outside, the pressure will always be lower once the water starts spinning, there for keeping the ball at the bottom... Where did my calculations go wrong? I'm confused... Lol But anyways, no matter what I have learned in my lifetime, I always seem to learn something new on this channel! Keep up the good work!

@AbrahimSabir 5 жыл бұрын

action lab: your explanation isn't accurate. it's more to do with liquid flow than atmospheric pressure. also you are conveniently skipping the fact that at very low pressure the water is actually boiling at room temperature

I think these conclusions are all mostly wrong and a little right. I think you will understand more if you dump a little glitter in the water.

That would harm the mouse. The animals he put in a vacuum chamber had exoskeletons, so they have a better chance in a vacuum chamber. While a mouse could survive, it will more inhumane.

That little experiment that you did with the straws also illustrates how carburetors work. As intake air flows at extremely high velocities into the barrel and through the venturi, it has extremely low pressure that sucks fuel out of the float bowl and into the intake to join the air rushing into the engine. Carburetors aren't used on cars anymore; they're exclusively fuel-injected now. But carburetors are still extremely common on GA aircraft, particularly those powered by Continental or Lycoming motors.
