Bernoulli's Principle Demo: Levitated Balls 

The entire Utah State University team that put this on gets an A+ 👏

3:30 and that is a true teacher

After watching tons of lectures I finally understand

Thanx A lot sir! Your demonstrations literally helping me in understanding concepts. 🔥🙏

Absolutely great experiment

At 1:55; Another video with *the most common misconception in fluids.* .. The centering is caused by the *acceleration* of the curved flow and is called the Coanda Effect, NOT Bernoulli's Principle. .. The statement at time 1:55 is *Incorrect* --> : "If you have a high velocity, a high airspeed, then you nave a low pressure."

If i had a teacher like you in my school days, I would have worked in nasa🤩

Omg that was dope

Thank you for this video! I've been so curious about this!

OH MY GOD. THIS IS SO COOL

thank you! I totally learned it. you're the best👍

Outstanding sir 👍👍

what is the cause that balloon is bouncing in the air?

The common misconception is that any moving air, such as from a hair dryer, leaf blower or your mouth, has a lower static pressure than the stationary air around it. This is not true and comes from a misreading of Bernoulli’s Principle and misunderstanding of how to apply it. There are several demonstrations that are misinterpreted to show the static pressure is lower. The moving stream of air from one of these is at the very same static, atmospheric pressure as the still air around it. It is NOT lower. Here is the correct explanation. This moving air has MORE total energy than the still air around it, not the same amount. This additional energy was added by the blower. The Total energy is the potential energy of the atmospheric pressure plus the kinetic energy of its motion or momentum. Each of these ‘blowers’ adds energy to the air in the form of static pressure. This internal pressure is higher than the atmospheric pressure outside it. For example, muscles move the diaphragm to squeeze the lungs. This increases pressure in the lungs. This internal pressure pushes more on the air than the pressure outside A pressure difference between two locations is called a Pressure Gradient. This reflects the idea that the pressure changes gradually between the two locations. Because the internal pressure pushes more on the air, there is a net force toward the lower pressure outside the blower. The air is free to move and is accelerated toward the lower pressure. This is Newton’s Laws in fluids. Air has mass. A Pressure Gradient provides a net force. Mass is accelerated away from the higher force, toward the lower force and gains speed in this case. This happens at the outlet of the blower and we have the stream of air starting internally at the higher pressure and accelerating to atmospheric pressure. That’s it. For those watching the conservation of energy rules, the TOTAL energy of air INSIDE the blower is the same as the TOTAL energy of the stream OUTSIDE the blower. The trip from inside to outside has no energy changes in that air. We see that inside the lungs, all the air has nothing but potential energy in the form of static pressure and no motion with kinetic energy - no dynamic pressure. All the energy in the lungs is in the potential energy of static pressure. The air gains speed (acceleration) as it exits, thus changing the extra potential energy of pressure into kinetic energy of the moving momentum of the air’s mass.

Does anyone know where I can obtain one of the demonstration devices that he uses at the beginning of the video. It looks like a children's toy.

Could this be the same phenomenon as the suspension of the rota-meter; flow measurement instrument?

Tanx sir

Could Bernoulli's principle apply to surgical mask?

Nice....

Hello, video very ineresanting!... Can this also be explained by effect's Coanda?

More viscosity than Bernoulli

Thanks sir from Pakistan ❤️

how can i calculate the angle that makes the ball fail ?

Hello Sir

Why does it start spinning?

And i can't believe i understood

I can understand it when i am 9... and now, i am graber: lol>

Universal Acceleration. #FlatEarth

It looks like CGI 😂

Tired of seeing so many videos ☹️
