One question, why does this easy explanation hold, if you can derive it with the conservation of energy and not with statistics? Why can you explain the functioning of airplanes with bernoullies principle, but also with newton (air will get pushed downwards so the plane will go up or lower pressure due to the roundness of the wing)? normally when there are two explanations they fit into each other and you've got a overall understanding of the problem if you know both explanations, but in this case of bernoulli, it confuses me.

I think there's a secondary component to twirling the hose that you might have missed. At that point I think it acts like a centrifugal pump and the inertia that you're creating in the air in the hose flings it out of the end also creating a low pressure behind it in the hose.

[@tobiasgraf9125]

Yes, that‘s exactly what I meant. The air trying to move to the edge/top of the tube creates lower preasure in the center/middle of the tube. This would also explain, why it worked so well in the beginning, compared to the first attempt in the car at lower speed.

[@adb012]

Another reason why this vacuum non-machine works, and possibly the reason why it works better than the hose in the car's window, is that by spinning the hose like that you are centrifuging the air away radially. This is actually how the pump in a vacuum cleaner creates the vacuum. It is a similar effect to this experiment: Have a heavier and a lighter stone connected by a string passing through a tube. Put the tube vertical with the 2 stones hanging from the string and the string will slide through the tube such as the heavier stone will go down and the lighter stone will go up. now let the heavier stone hanging and spin the lighter stone above your head and the lighter stone, as it is centrifuged away, will lift the heavier stone.

[@CosminRotaru]

Is it Bernoulli though? Or are you just throwing the air from the tube (when spinning it) and thus decreasing the pressure inside?

[@eyefindoutcdks5720]

I think it is both. It certainly is Bernoulli, but you are also throwing mass (the air) out of the tube. If the tube was filled with golf balls, they would be thrown out too.

[@Loganxmusic9339]

I think if it was just throwing the air from the tube, the effect would only last as long as there was air in the tube to move. So if it was just the air being thrown out, I would assume the effect would only last a second or two. Since the effects continue as long as you spin the tube, that looks more like Bernoulli's to me

The conservation of angular momentum is not the same as Bernoulli's Principle. The Torque is doing most of the work and the cup proves it.

Turbulence is the enemy of Bernoulli's Principle. He is acting as a blower fan. When hes in the car, it is Bernoulli's Principle though.

We use this concept in the natural gas industry when trying to pinpoint a leak (gas migrates underground, so higher gas readings in one spot doesn’t always mean you’ve found the leak). We use a purger, which is simply a Venturi that sets atop a 3’ aluminum tube with several holes at the bottom. When compressed air is pushed through the purger, from back to front, it creates the low pressure area where the restriction is inside. This creates the vacuum in the aluminum pipe and sucks methane from the surrounding soil. Once the soil is mostly clear, you can begin testing different spots to see where the highest readings are, and there is your leak.

[@Observ45er]

I think you are describibng an ejector pump which operastes by entrainment, not by the improper interpretation of Bernoulli's Principle.

@@Observ45er no, I’m not. It’s a Venturi, with no moving parts. It uses the effect noted in the video to create vacuum.

@@skoalsoldier Ok. So reading it again carefully, I see it's a pipe that shrinks in diameter, but then has holes to the outside pipe that is around in the narrow section. Then, I guess, the aluminum pipe is used like a vacuum cleaner hose? Is that a correct interpretation?

[@rijulreji]

I partially disagree. I strongly believe that the phenomena shown during rotation is due to centripetal force acting on the air inside pushing it out and thus creating a low pressure. I agree to the fact that most other stuffs shown in the video are due to Bernoulli's principle. Feel free to put your comments below (anyone). Happy to learn.

[@Joe-ks1jx]

Agreed. While Bernoulli’s principle is responsible for a fraction of the suction when he is rotating the tube, the majority of the suction is likely coming from the centrifuge effect. In essence, he created a single vane centrifugal compressor. Good explanation of BP, but partially misleading, at least when explains the rotating of the hose.

[@DrewskisBrews]

It would be interesting to know the tip velocity achieved by hand vs in car. Also in the car, having the window open changes the pressure in the cabin. Would be a more reliable experiment using some sort of wind tunnel.

[@jimmytvfclassic]

It's a matter to gain some air velocity, he just make circles with the pipe, and as he already proven in the car, it happens the same when going at a straight line, so centripetal force has nothing to do about it. Also when pushing air with the syringe, there's zero centripetal force, it happens the same thing (that one principle is a variant of Bernoulli actually, called Venturi effect, used in carburetors) He's actually creating the low pressure by velocity, that's the Bernoulli Principle at its best.

[@Joe-ks1jx]

@@jimmytvfclassic partially correct. Some of the suction is due to that, but most force is happening from centrifugal motion (not “centripetal” acceleration). Check out how a centrifugal pump or centrifugal compressor works. He effectively made a centrifugal compressor or blower.

You forgot to include radial acceleration of air in the spinning tube. As a kid, did the spinning around in the air but used a tube filled with water. Much of the pressure difference was caused by radial acceleration...Velocity squared / radius. As a kid, the Bernoulli effect didn’t have much effect. The tip velocity through air was not very fast but radial acceleration of water could easily lift feet of water or cause enough press difference to allow me to sling the water filled tube over my head. Bernoulli effect at low velocity would not cause enough pressure differential to lift that column of water.
