I honestly keep listening sk som sir
word to word and understanding it ...because i can never get a such brilliant professor.

[@moisessena1307]

sir plz explain why u put negative sign in wall shear stress?

[@johnrebeiro1066]

by mistake no negative

[@anshsinha9581]

at 1:08:25 , is the x on both sides of the equation same ? ( I think one is for plate area while other for boundary layer thickness )

abby yar yeh some sab kitny subject pahraty hain

[@NAYAN-t3e]

No surprise, he is a teacher of Fluid Mechanics, Thermodynamics, Heat Transfer & Turbomachinery. All these subjects are connected each other. So if some teacher masters in one of these subject then he should know about rests of subjects too.

Physical significance of Nusselt NUmber?

[@shubhamwr]

Improvement in conduction due to bulk motion (advection) of fluid. I. E. Improvement in heat transfer due to convection as compared to conduction

nice

I am watching this and sir is dead😔😔😓😓

Ye kya he kuch Samjh nahi aya

That's why it's called iit

[@shubhamwr]

You won't get anything if you are watching this to understand actual concepts after mugging up crap they "teach" In private colleges. You will get it if you want to brush up your concepts after studying for Competitive exams like gate from reputed coaching centres. Seriously colleges in india are so crappy... We need this level of education in normal colleges .... Unfortunately it's limited to few already brilliant or lucky students
