If you haven't already, I'd recommend you watch some lectures from Ron Hugo or Michel Van Biezen to prepare yourself. I took Fluids last spring and barely got away with my sanity and a high B. Best of luck to you!
Is is not the easiest stuff to calculate. But Thermal Dynamics and Fluid Dynamics is so much fun. I loved it. And I yous it all the time, even though it is not my work.
In microfluidics, the flow is always laminar because the diameter is tiny (less than a millimeter), so when you pump in two different fluids, they don't mix easily. If you look up "microfluidic chip", you'll see that most of them have a zig-zag shape. That increases the length of the channel so the fluids can diffuse into each other and mix evenly along the way (although there are other reasons why you would want to make the channel longer).
Best CrashCourse ever... EVER!!!! I love it... I think it is easier to understand stress and strain in the context of beam theory. And then defined a fluid as a solid not able to carry stress in tension. But this works too... I am looking forward to the FE and CFD videos it is going to be amassing.
I'm taking biomedical transport phenomenon and it is basically fluid dynamics.. I can assure you all it is not fun. Thanks crash course for breaking this down for others.
You can either watch these videos for overview skim which actually makes your sch/uni/coll lesson easier or you have already learnt these at sch/uni/coll then come and watch for better understanding. Both actually worked. I have already tried with chemistry, physics, biology, anatomy and physiology.
Great video, thank you. Just a small point I think might need correcting: In the diagram accompanying the normal strain equation, I think the subscript of the total length (on the top) should be T for total. This would differentiate it from the shear strain LF.
Ansys Fluent CFD is an interesting and helpful program for fluid mechanics/dynamics. Kind of wish they would talk about problems like cavitation or water hammer/hydraulic shock, unless that is in the next part...
I'd like to traslate these amazing series into Spanish since It's my mother tongue and I am really sure that some people around me or just that don't speak English would find them so helpful and interesting. Would it be possible drop the link here for that porpouse?
In the UK we don't graduate from college, we graduate from university. College is like an alternative for school, for A-Levels and other qualifications before you'd go to uni :P Must have felt weird for Dr. Shini to say that :P
could you help me a two question i need to understand them.. 1) Water flows through a pipe 4cm in diameter and 38m long between two tanks with square edged non projecting entrance and exit. The flow rate is controlled by a gate valve which when fully open has a loss factor of 0.32. What is the height difference between the tanks if the volume flow rate is 3.8 x10-3 m3/s. For laminar flow f=16/Re For turbulent flow f=0.08/Re0.25 Density of water, ρ , is 1000kg/m3, viscosity of water, μ , is 0.001Pa.s. 2) The viscous torque produced on a disc rotating in a liquid depends upon the diameter D, the speed of rotation N, the density ρ and the viscosity μ . The equation taking the form:- T = ρ N 2 D 5 φ ( ρ N D 2 μ ) In order to predict the torque on a 1.8 diameter disc rotating in water of density 1000kg/m3 at 129 rev/min a model is built to a scale of 1/4. The model is rotated in oil. Calculate the speed of rotation, in rev/min, for the model to produce dynamic similarity. The oil density is 785 kg/m3 and the dynamic viscosity of the oil is 4.7 x 10-4Pa.s. The water dynamic viscosity is 1 x 10-3Pa.s. thanks
shes explaining this fairly well, yet i still dont get a word she's saying, both because im american and i dont fully understand her accent and because i am an idiot.
I think it was meant to be a little jab at how fictional media portray quicksand, not an acurate description of how quicksand works. But yea, unless adressed in a later episode, it could cement false notions in some viewers.
Crashcourse could vastly improve their view count if they stopped this identity politics garbage and let someone host the show who is actually charismatic and entertaining to watch rather than someone who lets them feel good about themselves because they're fulfilling their PC quota.
This looks so simple, but oh boy, when you go deep into it...
LMAOOO
Trying to learn it for personal projects. Just gotta keep moving no matter how hard it gets.
I feel like stress and strain need a few episodes each. This stuff is so, so important.
I’m taking fluid mechanics during the spring semester and I’m so pumped for it. Lol pun not intended.
It’s fun and games until you hit navier-stokes
I'm starting my fall semester in 10 days and I'm taking fluid mechanics too. thank you so much I'm actually excited to learn about fluids now lol
good luck!

*The Bernoulli equation. Learn it. Now.*
Good luck! I always enjoyed fluid dynamics classes, it goes quick I promise 😊

I am taking Fluid Dynamics next Semester for my Engineering Studies. Thanks for the first insight, Shini & CC-Team :)
How did it go?

Normally I find the host speaks a little fast for me, but this ep was perfect. As always, full of great info.

We did this in a level physics I love it :)
CrashCourse, Are you able to make your content available on podcasts? I would love to listen to your videos while I work
Download the videos
download as mp3
My new favorite teacher😍
I learned more in this video than in half of my lectures on fluids mechanics
Can you guys make a linguistics course?
Flaming Basketball Club thanks,hope so

OMG where were you this year when I failed my exam on rheology?!
Great episode, as always.
My first time watching- thank you, crash course, for giving a platform to a woman of color in STEM. You’re being the change we need in the world.
she had a great series on Physics as well. She's not just a WOC, she's an incredible teacher
Nick C pretty bloody patronizing! You should check your privilege!
5:07 Osborn Reynolds should be the name of some superhero from MCU
Definitely needed this XD
In the UK we don't graduate from college, we graduate from university. College is like an alternative for school, for A-Levels and other qualifications before you'd go to uni :P Must have felt weird for Dr. Shini to say that :P
I had take the video 2x slower to make listening optimal since the delivery is very fluid.
shini's favourite episode
i love this!! this really interests me!!
How does the fluid(s) tendency changes in coating proccess of Poly films and membranes?
could you help me a two question i need to understand them..
1)
Water flows through a pipe 4cm in diameter and 38m long between two tanks with square edged non projecting entrance and exit. The flow rate is controlled by a gate valve which when fully open has a loss factor of 0.32. What is the height difference between the tanks if the volume flow rate is 3.8 x10-3 m3/s.
For laminar flow f=16/Re
For turbulent flow f=0.08/Re0.25
Density of water,
ρ
, is 1000kg/m3, viscosity of water,
μ
, is 0.001Pa.s.
2)
The viscous torque produced on a disc rotating in a liquid depends upon the diameter D, the speed of rotation N, the density
ρ
and the viscosity
μ
. The equation taking the form:-
T = ρ N 2 D 5 φ ( ρ N D 2 μ )
In order to predict the torque on a 1.8 diameter disc rotating in water of density 1000kg/m3 at 129 rev/min a model is built to a scale of 1/4. The model is rotated in oil. Calculate the speed of rotation, in rev/min, for the model to produce dynamic similarity.
The oil density is 785 kg/m3 and the dynamic viscosity of the oil is 4.7 x 10-4Pa.s.
The water dynamic viscosity is 1 x 10-3Pa.s.
thanks
You can work and research fluid mechanics (more deeply) following the career of Chemical or Mechanical Engineering.
Great video!
WHY DIDNT YOU GUYS MAKE ENGINEERING SOONER!!! ANYWAYS THANK YOU FOR THIS
Rho V D by Mu... why did you remind me??
now the nightmares will come back gain ;(
Wish this video comes out sooner
Hi this year I am taking physics 1 which textbook to buy would you recommend
Quick sand is dilatent or pseudo plastic?
HER: " YOU THOUGHT I WAS GONNA SAY PARALLEL STRESS, DIDNT YOU? "
ME: " YES I DID BABY... YES I DID "
4:20 that Engineato sounds kind of dirty lol
Thanks
we live in a society

@@bob-jones Thank you, Bob.
So Pressure is a measurement/type of Stress. Right?
Pressure is just a force spread out over a surface area.
Pressure is a normal stress, yes.
That's David Tennant in the animations.
Shouldn't that video be in crash course physical chemistry?
Can anyone help me. I want to further my education and become an engineer preferably starting in mechanical engineering and i have no idea what to do
Engineato! Meaning PLEASE??
Make more vids on engineering
Is pressure and stress the same thing? Their formula is same
Both of them exists at the same place. But the phenomenon is completely different.
Pressure is always compressive and perpendicular which is not in the case of stress
Wow 8 000 000 subs
Me, an almost *7th* grader: Mmhmmm yep. I actually understand some of this. This is actually pretty interesting.
Jane Redden that's pretty cool. We are living proof that science is for all ages.
im almost born
I am a blastocyst.
im -1/12
I am almost a 27th grader
Crash Course Geology!
Interesting
“Lit” as the kids would say!
Why turbulence?
chaos man. entropy. heat death is coming for us all.
Matter & energy can interchange but can they be created or destroyed? Do we know this answer & if we do, how do we know it?
Thank you! This helped me study for my English 12 B exam.
Is there any kind of physics that Newton doesn't have his hands in?
shes explaining this fairly well, yet i still dont get a word she's saying, both because im american and i dont fully understand her accent and because i am an idiot.
Sorry to anyone who has to take this class. I’ve already done so.
Hi there. So what is your result? Did you pass the course. Im going to take this class so Im a little bit cocerned . :)
Phát Phạm Hồng not hard until you begin learning about boundary layers and invicid fluids.
Thanks a lot XD . I'll keep that in mind.
Awesome
So that's turbulent and laminar flow. In-between is transitional flow, but don't worry about that, moving on
Anyone else reminded of Rakshata from Code Geass?
Why?
An engineer with similar character design.
Definitely, Rakshata Chawla who has beaten Earl Lloyd Asplund to creating energy wings
Oooow.. So that's why Japan's bullet train was designed like that. Making it faster.
Slow down good damnnnnnn
meaning that as the bottom plate is moving minuscule friction is transferred through the Air from the statistics nary plate to the moving one
Meaning that fluids can transfer friction from one object to another
cralix thegameking , sure,..have you ever heard of "wind burn"?

thank you for help.. i made it through the examination theory part.. all with imagination and your examples😁😁 no puns?😂😂
MKBHD
2020 anybody
Oh I was more interested in the Captain Marvel trailer that was played before the video!😂
Very nice lesson! Has anyone noticed how amazing and (scuse me) beautiful Shini is? 10/10 would take out for coffee and discuss research projects
Physics girl is cute but u r more articulate.
I like men
I know I should be paying attention and learning something, but gosh she is beautiful.
Bad people
*_flu_* ids
Huh?
you have a stunning face. just sayin.
EVERYTIME I SEE HER POST A NEW VIDEO, I START SWEATING 💦
I'm so confused.... 😕
The quicksand graphic is false due to buoyancy. Please do more vetting of the graphics, and have them work with physics people more.
I think it was meant to be a little jab at how fictional media portray quicksand, not an acurate description of how quicksand works. But yea, unless adressed in a later episode, it could cement false notions in some viewers.
This woman... She both annoys me, and attracts me. I... I do not understand these feelings.
I prefer non accent english

This guy is gross
Her british accent is distracting.
