Laminar Flow

Submitted by: ICN 9 years ago Science

I did not expect those dyes to do that.

haha thats cool.it happened because IT IS NOT WATER.it is CORNSYRUP which is very thick.he spun the liquids one way and spun them reverse the exact same way so they went back to where they were in the first place.it all a matter of science lmfao

It is just water and the injected red stuff is water with red dye in it. There is this videos`s brother on YouTube called "turbulent flow".

A low flow rates the layers of liquid flow over each other neatly and the dye slides between them. At higher flow rates, the shear between the different layers causes rotation in the flow this is the mixing.

The whole thing was sorted out by Osborn Reynolds in 1883.

These fluid dynamic effects are vital for planes flying, and other such stuff.

You can also get the laminar and turbulet effect from a tap. The glassy flow is laminar, the cloudy, turbulent (not dissolved water).

With non-mixing taps at the same flow rae you can get laminar from a cold tap and turbulent from a hot one, but don`t get me started

IkeRay above explained it correctly. Both liquids were corn syrup. Only the ones added later was dyed different colours. So all liquids have the same density.

Now if it was moved slowly, and returned back slowly all particles will come back to their original positions, including the dyed particles.

You will note that there were 2 people holding on to the jar to make sure that there was no movement on it. This was so that all particles could align correctly.

i think it`s because the dyes have different densities explains why they stack onto each other.
cool.

Maybe the one spin doesn`t count. It`s probably to reverse inertia.
Either way, excuse his one mistake. He`s clearly smarter than any of you.

dyed corn syrup in glycerin, with multiple cylinders capable of being turned. The colors are in seperate chambers so they look like they are mixing. The Laminar Flow will allow a droplet to be spread into a thread, and then return back into a droplet, but it won`t allow colors to mix, and then unmix. Fluid dynamics doesn`t work that way. In other words, it`s a trick, and not really as cool as it seems on the video.

^^^cornsyrup thats why the dyed syrup didn`t move up or down... anyway, pretty cool, I love Science!!!

it was okay but that wasn`t water they dipped that dye in what was it?

it has to do with the viscosity of the syrup. if turned equal clockwise as counter-clockwise, then the particles will return to their original location. he took a glass of corn syrup and put in drops of dyed corn syrup, thus same thickness.

knowledge is power, power is corrupt, corruption is evil, so the more you know, the eviler you are.

It`s not a trick. I`m not quite sure how it works and it`s bugging me. Anyone with higher than a high school chemistry/physics class want to explain? I always like reducing my ignorance. Ignorance is a blight on the world.

"Emoberry they put dyed corn syrup in if you listened"

I`m pretty sure she meant what`s the liquid they put it (the cornsyrup) in, like she said.

I thought something like that might happen, but I secretly deep down really wanted to see it blow up or something.

the fluid flows in parallel layers so that there`s no disruption between the layers. yay science

It`s not what I was expecting at first, but after he turned it backwards, I knew what was going to happen.

And he needs to learn how to count.

The video wasn`t reversed. I knew what was going to happen because I remember seeing Mr Wizard do something like this once.

He messed up the counting, but other than that, I guessed that would happen as soon as he said they were gonna turn it backwards...

I don`t mean to be anal (ok I do) but he rotated it 6 times. he realized it @ the end when he had to rotate it one more time. Now that I got that out of my system... I thought it was pretty cool.
