A portion of this video was sponsored by loda

00:04

This is like a scientist trap.

00:06

It certainly is; case in point, that is Space Station commander Chris Hadfield

00:17

What this isn't is turbulent. Nope, this is largely laminar flow.

00:22

“Did somebody say peculiar flow! ?”

00:24

no i dont

00:25

If you didn't know, Destin from smarter every day loves laminar flow,

00:30

where all the particles of the fluid move parallel to each other in organized layers or laminae

00:35

look at that it made a bubble!!!

00:38

Where I live people will roll down the window in their car when they see me in the street

00:42

and they will scream “turbulent flow” to me

00:45

That happens, that happens in Huntsville. Yeah.

00:48

Here- Here's my argument to you, Destin

00:50

nashe

00:54

Okay.

00:55

but turbulent flow if you make that effort is actually more awesome.

01:00

Um...

01:01

no.

01:03

Turbulent flow is not better than laminar. It is awesome

01:06

But it is not better than laminar flow.

01:09

Can I just say I get it

01:10

I get where Destin is coming from

01:12

I mean laminar flow is pretty and it's well behaved,

01:16

Meanwhile turbulent flow is a mess in more ways than one.

01:20

I mean, there isn't even a universally agreed-upon definition of turbulent flow.

01:26

You know it when you see it

01:27

[Laughing]

01:28

Hahaha, So that's the deal with turbulence, you know it when you see it?

01:30

Pretty much. Yeah.

01:31

So instead of a formal definition, in this video

01:34

we are going to build a checklist of characteristics of turbulent flow,

01:39

so that you know it when you see it

01:41

and the first characteristic of turbulent flow is that it is unpredictable

01:46

That's right. Turbulent flow is messy it's unpredictable.

01:49

It is literally definitionally chaotic

01:52

meaning it is sensitively dependent on initial conditions.

01:56

So if you were to change something somewhere in the fluid

01:59

well, it would completely change the final state

02:02

and that means you can't make predictions with turbulent flow

02:06

All you can do is speak about it statistically.

02:09

I mean, there are the Navier-Stokes equations which are meant to govern all fluid flow

02:13

Including turbulence, but they are notoriously difficult to solve.

02:18

In fact, there is a million-dollar prize

02:21

for anyone who can even make progress towards getting insight into these equations that would explain turbulence,

02:29

so yeah, I get it, turbulence is a mess,

02:31

laminar flow is easy to love

02:33

It's like the bell of a ball

02:35

whereas turbulent flow is kind of an ugly duckling

02:38

But in this video I want to transform that ugly duckling into a beautiful swan

02:43

I want you to see that if you make the effort

02:46

The love you can have for turbulent flow is so much deeper and richer than that superficial fling you have with laminar flow

02:58

You are looking at the motion of air in a room, which is generally turbulent

03:03

the physics girl and friends imaged a cross-section of air using a fog machine and a laser sheet

03:10

one of the defining characteristics of turbulent flow is that
