Super great video...and I enjoyed the soundtrack since it was unusual for this kind of video. Really good at explaining a concept that a layman like me found hard to understand
The first song is "Hot Like Sauce" by Pretty Lights. If you like that song, Check out "I Know the Truth," and "Forever Lost" by them as well. Well done on the aero explanation! Here's another unsolicited opinion to add to the youtube consortium: this is technical information and Electric Dance Music (EDM) is similarly technical. Appropriate soundtrack selection!
Just because the Reynolds number is less than 10^3 or greater than 10^4 does not alone determine whether the flow is laminar or not. this also depends on the geometry that the fluid is flowing through.
The presented values of Reynolds numbers to distinction between laminar and turbulent are valid for air without walls. The transition occurs at different values in other conditions (liquids, pipes, etc)
Do you have a reference for the footage of creeping flow past an airfoil at 1:04? I am interested in this flow condition for a project I am working on and would like to follow up.
I agree that the music is really not required. The short videos of wind tunnel tests also did not help me understand the content. Less misguided showmanship and more content is required.
You had mae a missleadings. In your video, you showed two laminar flow, but those are not laminar flow. Thoes are Hele-show flow, which is a kind of potential flow.
Nice video even physic is not quite correct. Re is not ratio of visco to inertio .This rate is the same order across very wide range of Re numbers :-).
Could you please explain to me why is it when the flow changes from turbulent to laminar, it requires a lower velocity than the one needed when it goes from laminar into turbulent?
1:05 A Trefftz-plane analysis would reveal that this airfoil is making near-zero lift despite its obvious angle of attack (w=0). Kutta condition? What Kutta condition? No flow separation = No Lift...
I calculate some figres for heat exchanger (shell&tube). I am bound to calculate Re in space between tiny tubes (were cooled fluid flows). My query is which diameter I should use for Re:ds= 4*Surface/circuit or get it from surface: ds= (surface*4/pi)^0.5 ?
If you know what type of oil you are dealing with you should be able to find it in it's viscositydiagram. Take note that viscosity varies with temperature.
I have a project where I need to heat large amounts of water (1.2 million gallon tanks) with no electricity or combustible gases. Basically I have large water pumps capable of moving water at 1200 GPM (+) capable of pressures up to 300 psi. They are driven by 350hp diesel engines. I need to convert that mechanical energy into heat. I was thinking via cavitation. I am in no way an engineer and have very little engineering back ground. So any ideas out there? I am looking for someone to help me design a system to take the cold water out of the tank and return it to the tank as warm as possible.
Thats the problem with engineers, you guys have grown boring and have a way of removing fun from everythin, who the freak cares if he uses dub step music in the background
When you gotta teach fluid mechanics at 5 but got an electronic music festival at 6
lmaooooooooooooo
😂😂😂
hhhhhhhhhhhhhhhhh
🤣🤣✌🏻
Like Seriously 😂😂😂😂😂
The combination of music and information was like a trippy learning experience. Loved it. Thanks for the awesome vid.
dubstep engineering
Loved how Skrillex was somehow brought into a fluid mechanics video.
I've taken drugs to help study for my finals tomorrow, putting skrillex as background music to Reynolds N video. This guy understands.
Man iam high seeing you after 8years
@@youcompleteme2602 im high seein ya after 2 years
love the background edm. Keeps me awake when I'm tired of studying fluid mechanics.
Great presentation. Great music. Great visuals. Very informative yet entertaining as well
The music was the right addition to the basics presented - nice job - you introduced this from a nicely aesthetic perspective
Super great video...and I enjoyed the soundtrack since it was unusual for this kind of video. Really good at explaining a concept that a layman like me found hard to understand
I apreciated the video, and thought the dubstep music in the turbulent flow moments was a nice touch.
Was the sound recorded in the Toilet?
TEMAZO att JV
give these guys a freakn award!!!! Nice job guys!

Loved the combination of music and teaching. =D
Great video except... why the music? It's really not necessary...
It makes it more interesting, for me anyway.
There was no reason for the music to go THIS HARD
Appreciate the info, music did take away from over all presentation a little , but enjoyed none the less {=(THUMBS UP)=} !
All the party poopers in the comments. Go dubstep engineering!😎
Just because the Reynolds number is less than 10^3 or greater than 10^4 does not alone determine whether the flow is laminar or not.
this also depends on the geometry that the fluid is flowing through.
Between 10^3 and 10^4 the flow is in transition.
The presented values of Reynolds numbers to distinction between laminar and turbulent are valid for air without walls. The transition occurs at different values in other conditions (liquids, pipes, etc)
Do you have a reference for the footage of creeping flow past an airfoil at 1:04? I am interested in this flow condition for a project I am working on and would like to follow up.

Awesome video, it was very helpful to understand this number :') and I've been trying for a while now.
where are the color-full neon fluid mechanics videos from? would love to study them further
You want link ?
This comment is hella old but if anyone sees this comment in 2020+ the app Wind Tunnel is amazing for visualizing aerodynamics simulations.
For laminar flow is Reynolds number smaller than 2100 and for turbulent flow, greater than 2300 or so... depending om many other factors...
This song takes me back 😊
osam the music nd animation make the study more interesting... keep it up
Better 10^3 and 10^4 flow is in transition. A bit of both depending on the parameters.
As soon as I heard scary monsters and nice spirits I knew this video was old!
That music bro + learning...awesome
You had mae a missleadings. In your video, you showed two laminar flow, but those are not laminar flow. Thoes are Hele-show flow, which is a kind of potential flow.
I came for the knowledge and stay for the music.
Nice video even physic is not quite correct. Re is not ratio of visco to inertio .This rate is the same order across very wide range of Re numbers :-).
Nicely explained. I should have watched this earlier.
unfortunately in the scale i work in, the reynolds number does not apply any more. Its just needs space to develop the clouds.
i simply have no space.
Ain't nothing like a little skrillex when learning fluid mechanics
Good To Understand
what song was used between 1:43-2:03? thanks
beautifully illustrated
Damn that flow hit so hard it needed a drop
Could you please explain to me why is it when the flow changes from turbulent to laminar, it requires a lower velocity than the one needed when it goes from laminar into turbulent?
Rastko possibly something to do with drag?
1:05 A Trefftz-plane analysis would reveal that this airfoil is making near-zero lift despite its obvious angle of attack (w=0). Kutta condition? What Kutta condition? No flow separation = No Lift...
The atomic mushroom of a nuclear explosion is also a turbulent flow
Great video thank you
what is with the music? it was indeed a turbulent way of learning
I calculate some figres for heat exchanger (shell&tube). I am bound to calculate Re in space between tiny tubes (were cooled fluid flows). My query is which diameter I should use for Re:ds= 4*Surface/circuit or get it from surface: ds= (surface*4/pi)^0.5 ?

first song? :)
How do you get the viscocity value of an oil running through a pipe?
If you know what type of oil you are dealing with you should be able to find it in it's viscositydiagram. Take note that viscosity varies with temperature.
Incredible annoying sound...
awesome soundtrack
Thanks for the video.
I love that music
The inane music really detracts from the video.
so, what happens when the number is between 10*3 and 10*4?? is it Reynoldsly undefined??!
Transitional flow
hi , just wanna say thx for sharing this, godbless
Nce presentation, but terrible, unappropriate soundtrack, It even masks the voice. Next time better sound, please
Meanwhile ..when having attention towards stuff
Music be like: areee meko to sun jara 😂
Absolute tune
Fuckin' Skillrex gosh damn it... Good video though.
good stuff.
Your my hero
I want this program..
Y U NO CITE MUSIC?? Cuz it's kinda cool... *_^
Thx!
Bobing to a engineering vid
a teacher showed this vid in class, and the music was so god damn cringy holy fuck ive never cringed that hard in years

Prof Burg sent me
God this is so 2000's
What if 10^3
Never mind, someone already answered in the comments.
ME HUBIERA GUSTADO QUE ESTE EN ESPAÑOL
The goofy music tho
weird music but ok I learned a lot
You're cool
1:05 Hele-Shaw flow FTW. Also, the Kutta Condition is apparently overrated lol
Do I wait another 10 years to get to an aerospace company in person? they too busy to be on youtube.
👏
The music choice is so 2012
ah yes 2012 music
skrillex!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
apreciación por la musica de skrillex
salut ludow
goofy aaah video it was good tho
yasss omg
i like the dub-wub-wub
Ahhhhhh that music is obnoxious!
Skrillex
Skrillex....
Can you dumpstep my lectures too pls im begging you
SKRILLEXXX!!!!!!!!!!!!!!!!!!
👉♾👈
Whenever you make an educational/informative video, for god sake please don't affix EDM in the background.
Holy fuck, that music sucks.
horrible music ( horrid autotune, and other issues.) Clear explanation though :)
Autotune? Theres no singing
make a great video and then fuck it up
I'd rather watch how to basic
speak properly
Thats the problem with engineers, you guys have grown boring and have a way of removing fun from everythin, who the freak cares if he uses dub step music in the background
You're looking for artists. Usually Engineers just want to get the point across so the artists can go out and use it for something pretty.
