- Welcome to another lesson in Introduction to Aerospace Engineering!
In this video you will learn what viscosity is and what is the difference between viscous and inviscid air flow.
Let me know what you think of the video in the comments and subscribe to my channel to stay tuned!

How much more viscous is honey compared to air?
Viscous of 🍯 is 1,00,000 times the viscous of air💨...
but why the viscous effect can be neglected in the inviscid zone?
Because the gradient of velocity change is not as big as compared to high velocity.
10000 times as per the video and what if the no slip condition is not taken in account what will be the senario
That's a question for a separate video))
I cant express how grateful I am for these videos
Thanks so much!
I love the simplicity of your explanations. Where were you when I was at uni, oh yes not born lol
You explain the topics so good
Waiting for your further videos !
Thank you for watching! Glad it helps :)
Amazing video
What a wonderful explanation!!
This was good. I understand now
Great effort congrats
God bless you
such simple n sweet videos! :)
nice explanation sista ,expecting more videos in same style of explanation
Thank you, I will
Thank you Ma'am Aliya!
You're welcome!
nice explanation..
Nice explanation please upload atmospheric wave
Thanks! I will try as soon as possible
1:49 100,000 times more viscous than air
a wonderful explanation if possible please make the video for the CFD
100 time thanks ❤❤❤
Most welcome 😊
damn, this was very clear! but I have a question, can the same explanation be used to explain any type of viscosity such as oil and water?
Of course! Viscosity is a property of any fluid. But some fluids can't go as fast as air can go, so sometimes it's easier to describe the motion of other fluids. Air is the most complicated
@@AliyaBurkit great! thank you so much for your help, you are really helping me a lot in my fluid class!
@@diegoguatemala1520 Glad to help!
Thx
Thank you for watching!
Pretty good explanation of viscosity.Sad to see that it's so underrated
thanks, i learning something new
Tq
Aliya, do you have any ideia about how many layers are necessary in order to air get infinity velocity? It is not necessary to be precise, just to have an idea.
There is of course infinitely many layers, since the molecules of air are so small. But the thickness of the boundary layer will be different for different freestream velocities. The higher the freestream velocity, the thicker the boundary layer will be.
@@AliyaBurkit Thank you very much.
Thanks for your videos, I just wanted to tell you that your explanations are always very helpful, cheers from Spain!!
@@nicolopradella7091 Indeed!I totally agree with you.
@@AliyaBurkit Cheers from Brazil!
nice thank you👌
Thank you too for watching!
you are sooo GOOD...❤❤
comedy always a winner to break the tension
Thanks!!
Welcome!
So V Infinity means velocity at the infinity not infinate velocity ,I am not familiar with aerodynamic terminologies so it confuses me
Ma'am, what are the fundamental equations of motion describing the fluid flow? I am new to this topic.
Air is 100,000 times less viscous than honey.
Exactly!
Nice presentation. But your editing is not like that. Because is difficult to understand.but your explanation is good 8/10thank you.
what film is this? the clip you put right at the start?
Van Helsing (2004) :p
ليه ما مشطتي شعرك قبل ماتتفلسفين
I don't understand 😅
Ne anlatıyorsun ablacım sen ?
If conservation of momentum is rho.del.ui/del.t + rho.uj.del.ui/del.xj = rho.f - del.p/del.xi; in the convective (advective if you like) term, why is the first u term uj, not ui?
