Introduction to Fluid Mechanics and Fluid Engineering by Prof. S. Chakraborty,Department of Mechanical Engineering,IIT Kharagpur.For more details on NPTEL visit nptel.ac.in
Hey Juniors. I was here while I was preparing for Engineering Entrances - GATE/ESE. One Day you will also pass through these days ,trust me all this hardwork will pay off. You will be a great Engineer... Lots of Love, Hirak. Feb 4,2020. B.Tech 4th Sem, T.U, Assam.
Excellent video..Rest all the videos were simply not upto the mark but this one has it.. Thank you sir for not reading out whats already written in the books but explaining them
At @32:00 if pressure term is more dominating than viscous and intertia term how can it be zero? Mathematically i know we can ignore such terms but if pressure grad itself stands to zero then how can other terms be more smaller/less? Is it like if pressure term is 0.01 then viscous terms are 0.00001? Also in X & Y momentum equation we took order of pressure energy as order of kinetic energy. Well thats alright but why X comp of velocity is taken? why not velocity V ( vector V)
why cant we divide inertial term by viscous term to have an idea about reynlod no. , which by the way come in form of (del)^2/L ..Which will be less than 1 ?
due to roughness of the plate or surface the nearest molecules of fluid will stick with surface, and the molecules which are just away from surface are due to cohesion between the molecule to molecule.....the velocity varies

Velocity v is very small compared to u. This means u is dominating with respect to v. Therefore in the two equations, dp/dx will have a larger value compared to dp/dy in the other equation. This term WILL have some finite value, but for engineering purposes, it's value is insignificant with respect to dp/dx. So we take dp/dy = 0
Thats the reason you are in a private college. You won't get a better illustration about this topic in RUclips. I believe you may end up as a non technical person. And don't give any slangs about any IIT faculties. Because to do that you do not have that capability

nice bro might help a lot of people. I bet you wanted someone to say this to you when you were preparing!

Thanks
My right ear liked this video.
🤣🤣🤣🤣
🤣🤣
I thought my left bud got out of charge 🤣
Thank you so much for such a good explanation. No other video on RUclips on boundary layers actually helped until I came across this.
take a bow !! One of the best profs for fluid and thermal science !!!
8:30 Intro, 23:45, 43:40 Boundary Layer Equation Y dir Momentum Equation, 51:48 $/l~Re^(-0.5) 😱😱😱😱 , 48:23
Excellent video..Rest all the videos were simply not upto the mark but this one has it.. Thank you sir for not reading out whats already written in the books but explaining them
thank you so much for such an amazing explanation.... haters will hate anyway...
I didnt realized that my left earbud fell off while watching the video. great explanation btw.
there is a reason why everyone wants to study engineering at iit , the quality of teaching is sooo good
Ya u rgt
Hey dude this is scam, I'm from iit Madras, prof don't give a shit about teaching, just one of 100 will be like good teacher in

@@ramanasandilya1567 awww did you claim the SC/ST reservation to get into IIT ?
@@satyanveshisingh5047 no i am a general category bhramin student , thank you
Clear all concepts, excellent teacher
Great explanation! Very well explained the physical meaning of boundary layer theory.
God damn this was great! I wish this guy was my teacher

Very nice video sir, the teaching and explanation of the matter was was very good. Thank you sir !
Great explanation sir.
Excellent Video !! Very well explained ..
Thank you, sir. You are explaining great.
this guy is a legend
Amazing explanation
Thank You Sir
Very good explanation sir...
why cant we divide inertial term by viscous term to have an idea about reynlod no. , which by the way come in form of (del)^2/L ..Which will be less than 1 ?
excelente explicación saludos desde México
GREAT VIDEO!!!!!!!!!!!!!!!!!!!
great video ....
If pressure term is dominant then how it signify that it doesn't depends on Y coordinate???
Thanks a lot
Thanks
sir
why does velocity at bottom of canal or any plate will be lower than top surface
is there any relation...
due to cohesion between plate(solid) and 1st layer of fluid with plate
due to roughness of the plate or surface the nearest molecules of fluid will stick with surface, and the molecules which are just away from surface are due to cohesion between the molecule to molecule.....the velocity varies
because of viscosity is more. viscosity acts like a friction and it oppose the layer of fluid flow over on it
Is the video giving voice only in right ear,how this??
Thank u sir
what happens to velocity componant which is perpendicular to plate
There won't be any velocity in y dir
There wont be any velocity in Y-direction because we assume No-penetration condition for the flow
Thanku
really good video.
What is the relation between x and y

AT 35 HOW COME PRESSURE GRADIENT IS ZERO . HE SAID DOMINATING WHAT DO YOU MEAN BY DOMINATING
Velocity v is very small compared to u. This means u is dominating with respect to v. Therefore in the two equations, dp/dx will have a larger value compared to dp/dy in the other equation. This term WILL have some finite value, but for engineering purposes, it's value is insignificant with respect to dp/dx. So we take dp/dy = 0
Can a boundary layer has infinite thickness?
Bilal Shabbir probably when viscosity of fluid is infinite
No its close whn local velocity reach.
yoo
What will happen at low Reynolds number?
No sound and the quality of the video is too poor.
your right ear or earphone must not be working properly
any one recommend a text book for this
INCROPERA
Sound is not good
48:23 GATE question
Poor video quality.Please improve the video quality and there is problem with audio too!
im not sure about what youre saying here, i think some of the info is incorrect
Euan Povey, really? Then can u point out which infos here are incorrect? i bet u cant
Isse acha mere clg ke prof padhate hain aur mai private clg ka hun
Thats the reason you are in a private college.
You won't get a better illustration about this topic in RUclips.
I believe you may end up as a non technical person.
And don't give any slangs about any IIT faculties. Because to do that you do not have that capability
there is difference between fooling and explaining real concepts.
