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..

[@alwinantony6852]

Very very useful and informative sir, by the grace of God I understand Hindi though I am from south

[@surajsahu596]

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.

[@akhilreddy7408]

This is like a twist in movie i thought the derivation was for the drag force but not omg

[@121aayushpatel4]

Such things happen if derivation is long😎😎

[@unwanshakib8828]

After watching your vedio sir Concept is crystal clear Thanku sir

[@aggarwalprateek6]

Thank you sir for detailed Explanation .

[@ashishyadav1035]

Thanks for brilliant efforts...

[@arandomchannel56]

Best video on boundary layer on KZbin

[@chinmaykolekar8008]

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

[@jaypatel7632]

Awesome👏✊👍..

[@jaisinghverma3716]

Thank you Sir. Great explanation.

[@er.akyadav4816]

Sir, what is difference between friction and drag force?

[@aggarwalprateek6]

Drag force is divided into 2 forces 1.) Skin friction Drag(friction force) and 2.) Pressure Drag

[@15-kundankrishnan6]

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)

[@Soubhagya_CHE]

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 ))

[@___danish___]

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

[@divyanshujaiswal4100]

Brother can you elaborate this segment

[@ankushverma450]

Thanks a lot sir

[@suryakantsahu3018]

Sir there is a mistake near 35:15 .. u say incompressible but write compressible .. Thanku sir for great lecture series

[@balkrushnaparkale7094]

Thanks sir

[@pizushkarmakar9596]

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.

[@manishrajput3860]

Sir when will you start uploading the thermodynamics videos.

[@maharudrashinde07]

Sir thermodynamics me video apload kro? Venugopal sir aap bahut achha padate ho

[@khageswarbhuyan2358]

Sir,in this Video ...net change of momentum in ABCD, IS Doubtful.... Please clear it ... 31:29 Momentum influx From BD..

[@ajinkyasuryawanshi2821]

Bhai vo momentum influx BC hai

[@terguliruk1118]

That's BC..sir mistakenly written BD

[@mithileshshukla8722]

Good effort sir

[@jnanabhaskara7939]

Sir pls provide complete open channel flow videos

Sir why did u stop thermodynamics lectures pls upload next lecture of thermodynamics pls sir.....

[@bajrangeekumar7353]

u r the best sir

[@ranjankumarjena4337]

Sir when will u upload open channel flow?

[@sumeetchakraborty8480]

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?.

[@peacemaker393]

Very thankful Thank you so much sir..

[@tarun.s1493]

Simply thankful 2 u dear sir

[@panditg2393]

Best👌

[@ashwinjohn2193]

Thanku mahn

[@ankushverma450]

Thanku sir

[@videos4]

Sir what is the use of coefficient of drag, local or average, i mean significance

[@shubhamwr]

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

[@Madhus0428]

How Drag force and momentum exchange are in same direction?

[@er_shubham_ragad3303]

Yes sir I am exiting for boundary layer separation.

[@rajkushwah2017]

Sir fluid mechanics and fluid machinary kab tak khatm ho jayegi. ????

[@9harminder]

sir ,when will dimensional analysis be taught??????

[@y48d]

Sir, you have explained very well, thank you very much Sir... Assalamu Alaikum....

[@rishabhpandey3880]

sir, why did yu left the course in between? Please finish the subject.

[@sourabhdesai2108]

Sir OPEN CHANNEL FLOW next chapter lijiye plzz.....

[@ajaygopal2723]

Hmm sir open channel flow kafi imp topic h Please agli video us pr dijiye..

[@AshwaniKumar-tj2pw]

Please upload civil engineering lectures

[@cocgaming5288]

boundary lsayer equation kab hoga

[@amananand9434]

Mja aaya sir padh ke

[@neerajkandpal5892]

Sir please doing couintinoue

[@sandipmishra3141]

Sir age video upload kijie plz sir.....

[@aswarthakappala690]

Forces on submerged bodies videos please

Sir uploaded. Further videos plz

[@ajaygopal2723]

Thnku sir Nd sir open channel pr bhi video dijiye . Plz plz plz ..sir..🙏🙏

[@satya8497]

sir please open channel flow ki video bhi daal do

[@rahularayn355]

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

[@gauravshukla2778]

Haan sir thermodynamics bhi le kar chaliye plz

[@galacticsapien9625]

Thank you sir ,huge respect🙏

[@MUKESHYADAV-ky2mh]

sir momentum ifflux from BC ke equation mai u^2 ana chahiye kya aisa shi hoga

[@musicwithamarvibhuti3176]

Dear sir, boundary layer thickness ka pura derivation bataiye na.

[@ashishkumaryadav9160]

Why flow separation occurs

[@rajat0610]

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?

[@srikanthpamujula1689]

Sir plz upload valves tutorial sir

[@davinderpalsingh4300]

SIR U AND UR TEAM ARE DOING WONDERFUL JOB AND SIR ONE QUERY WHY BOUNDARY INCREASES DOWNSTREAM

[@atiqueahmad8965]

pls sir theory of machine k vidio par kam kijiye I special request for all gate academy team

[@AbhishekKumar-vs8nh]

Sir thermo or theory of machine ke v video upload kijiye

[@nandyadav6982]

sir plz hyraulic machine ke video upload kar dijiye jalid.

[@mitbakhai6205]

AT 35.46, there is a dx at last which is suddenly missing, will you please specify where did it go ? thanks

[@santoshkumarrai7266]

It was written by mistake. U can see in the previous step, dx has been cancelled out

[@kshitizbhakwala2687]

The boundary layer on a flat plate....ye vedio kh milega
