This is also how the emergency slides on airplanes inflate. There is a small compressed gas chamber, but most of the air is the surrounding air that has just been blown in.

Thank you sir....i just bought air circulation fan... For 2 weeks i experiment with this fan...now i know how to use it using this bernaulli principle...it got better than old style stand fan...more cooler...less humidity....

[@jefflebowski3784]

Effective demonstration

[@sptownsend999]

There's actually another video somewhere on KZbin that the guy tested the optimal location of a fan in relation to a window by measuring the airspeed of the incoming air. The more air that comes in indicates more air being blown out. He found that putting a standard box fan about a yard (or a meter, for those of who who don't have a flag on the moon 😝) away from the window, or about the diameter of the fan, produced the most air circulation.

[@wolf_science]

I’d love to see the post and plan on coloring this topic with some more videos in the future

[@joemccarthywascorrect6240]

I just use Bernoulli’s Principal yesterday at work (I work at an industrial/agricultural/landscaping equipment rental/repair business) and someone had put the wrong fuel in the tank. After draining, there was still a small amount of contaminant in a depression in the tank (the tank had been warped over time, probably due to mishandling/abuse). I could have dragged a Jack over and tilted the machine to try to get the fuel to run to the port, but instead I took a length of fuel line and stuck one end in the depression, then took a blowgun and blew a get of air across the other end at a fight and for and vacuumed the rest of the fluid out. Of course, there was an impressive white cloud of atomized fuel vapor as a result, so don’t try this at home- I’m a “professional” 😁🤣😂🤣

[@wolf_science]

That is fantastic! Thanks for sharing! Might have to use your comment in a future post!

[@joemccarthywascorrect6240]

@@wolf_science see? I really WAS paying attention in sophomore year 😁👍

[@jameswright4732]

I loved this demonstration as a kid! However, note that this phenomena has nothing to do with Bernoulli's principle. It's actually due to turbulent entrainment. Your breath creates a turbulent jet, and that turbulence causes mixing with the surrounding stagnant air. The momentum from the jet transfers into the stagnant air, resulting in a decreased jet velocity, but an increased volumetric flow rate.

[@itsnotallrainbowsandunicor1505]

This is not bernoulli, but a phenomenon called entrainment. This is the same phenomenon with air over aircraft wings where more air is pulled downward to help with lift. Bernoulli has no place with airfoils since we are not working with restrictions such as venturies, but mire to do with a fluid going over a curved surface.

[@bigl6322]

Nicely done sir!

[@paulofurtado4925]

You can use that principle to cool down your house, on one side of the house open a window just enough to the size of the fan, then point a fan outwards maybe 2 feet from the window and turn it on, open the windows on the other side of the house or even on the same side, close doors or windows for rooms that have no one are are not needed to cool down to create a better draft.

[@nagaviper1169]

We learned about Bernulli's principle in flight school. It's what creates lift. And can cause airplanes with carburetors to get carb ice on a warm day.

[@tetrabromobisphenol]

Sorry to tell you but you were badly misinformed, but I don't blame you I blame your instructor. Bernoulli's principle does not predict lift AT ALL. It has been misapplied for years by "well meaning" people who don't have a clue what they're talking about. Lift is generated by a net circulation or a 'turning' of flow. See: www.grc.nasa.gov/www/k-12/airplane/right2.html
