I don't you have any idea or not but because of you . i love fluid mechanics.. great job sir..you are like an angel for me ..pls sir always done this wonderful job.and blessed us..thanku sir..
Sir please upload the videos of rest chapters as soon as possible.These videos are really helping us for preparing GATE & ESE. And also upload lectures of SOM.
Best explanation of derivation sir, hame such me nahi pata tha ki DFD me negative kynu aya in college time but apne ese bahut acche Tarah se kynu ata hai ye bhi bataya,thanks a lot sir
Friction is an opposition offered to the relative motion of an object wrt an other object ...... friction always opposes the motion no matter what.... However, in case of drag, drag is a force which acts along the fluid motion, which means if an immersed object moves in opposite direction to the flowing fluid, the drag will oppose the motion of the object, but if that object moves along the motion of the fluid, the drag will support the object's motion . (( Correct me if I'm wrong ))
At *22:52* In the Taylor series expansion you have written d(Mbc) = d(Mad)+del(d(Mad))/del(x)×dx. But the expansion equation which you have written is in Integration form, So I guess you should write Mbc = Mad+del(Mad)/del(x)×dx
the resisting shear force is negative. the change in momentum producing the drag force and resisting shear force is resisting the plate to move. As the direction of resisting shear force is opposite to rate of change in momentum that is why there is using the negative sign.
Sir me self study student hun aur gate academy lecture vedio follower hun ...me request karata hun ki ap FM HM ka open channel flow and HYDRAULIC MACHINE lecture vedio upload kare
sir please give the topic wise question bank so our understanding to subject/topic increases and will help us to know the types of models a question can be asked
We have not considered considered mass flow rate constant in displacement thickness but while calculating momentum thickness and K.E thickness we considered the mass flow rate is constant why?.
Sir please complete subjects one by one. This will be helpful for those who watching the Lectures of subject ,right now we have to wait days to see the next lecture.
Sir please tell us when will you start turbomachinery if it will be late from your side then I will take reference from some other site...I am already waiting from last 2 months to finish fluid mechanics...
Sir first u said drag force is always in the direction of fluid flow.. And then in last part of derivation u took it as negative saying drag force is opposite in direction of rate of change of momentum... Can u explain this little
Sir in ur previous lecture module U had taken mass flow rate as a mass(roh.u.dA) while in this video u have taken (roh.u.dA) as mass flow rate. Why, please explain sir
In the equation for average drag coefficient, which area does A denote? If it denotes area of plate, can it be written as shear stress as shear stress=Fd/A?
I don't you have any idea or not but because of you . i love fluid mechanics.. great job sir..you are like an angel for me ..pls sir always done this wonderful job.and blessed us..thanku sir..
Sir please upload the videos of rest chapters as soon as possible.These videos are really helping us for preparing GATE & ESE.
And also upload lectures of SOM.
Very very useful and informative sir, by the grace of God I understand Hindi though I am from south
This is like a twist in movie i thought the derivation was for the drag force but not omg
Such things happen if derivation is long😎😎
Best explanation of derivation sir, hame such me nahi pata tha ki DFD me negative kynu aya in college time but apne ese bahut acche Tarah se kynu ata hai ye bhi bataya,thanks a lot sir
After watching your vedio sir
Concept is crystal clear
Thanku sir
Thank you sir for detailed Explanation .
Best video on boundary layer on RUclips
Sir, what is difference between friction and drag force?
Drag force is divided into 2 forces 1.) Skin friction Drag(friction force) and 2.) Pressure Drag
Sir, friction is the opposing force of any motion....Whereas drag force is also a kind of frictional force offered by fluids only(like air & water)
Friction is an opposition offered to the relative motion of an object wrt an other object ...... friction always opposes the motion no matter what....
However, in case of drag, drag is a force which acts along the fluid motion, which means if an immersed object moves in opposite direction to the flowing fluid, the drag will oppose the motion of the object, but if that object moves along the motion of the fluid, the drag will support the object's motion .
(( Correct me if I'm wrong ))
Thank you Sir. Great explanation.
At *22:52*
In the Taylor series expansion you have written d(Mbc) = d(Mad)+del(d(Mad))/del(x)×dx.
But the expansion equation which you have written is in Integration form, So I guess you should write
Mbc = Mad+del(Mad)/del(x)×dx
Brother can you elaborate this segment
Sir there is a mistake near 35:15 .. u say incompressible but write compressible ..
Thanku sir for great lecture series
Awesome👏✊👍..
the resisting shear force is negative. the change in momentum producing the drag force and resisting shear force is resisting the plate to move. As the direction of resisting shear force is opposite to rate of change in momentum that is why there is using the negative sign.
Thanks for brilliant efforts...
No one can explain fm like u sir...

SIR U AND UR TEAM ARE DOING WONDERFUL JOB AND SIR ONE QUERY WHY BOUNDARY INCREASES DOWNSTREAM
at 29:29 it will be BC not BD
Static fld b real hota h kya... 🤔
35:06 incompressible .... Density is constant.... Spelling mistake ...
Nice observation bro
Perfect yarrr
Why flow separation occurs
