Sir when you have taken the case of absence of boundary layer then how the mass flow rate be ( density×b×dy×u) since in the absence of boundary layer there is no u (local velocity)
logically it would be the freestream velocity instead of local velocity component. otherwise, some assumption must be taken during the deviation of the equation or this proof might consist of an algebraic error. however, the final equation is correct which does correspond to the fact that a local velocity component is used in the actual derivation.
sir orifices chapter ke aage ke topics ki video bhi Bana dijiye jald se jald sir mere polytechnic ke agle week internal exam Hai to sir isliye thoda aur work hard karke vdo Bana dijiye
Sir ager plat hi nai hai to fir (u) kese ayega case 2 mai.... Uski velocity bhi u(Infinity) honi chaiye na
Sir, in Case 2, in the express for mass why you took u? It should be u( infinity) in place of u?

Yes sir pls reply this cmnt

Read momentum thickness definition
It is change in momentum of mass flow rate(with boundary layer) when boundary layer is present and absent.
Bro...utne hi mass ka flow rate .....once with u and once with u infinty
Do you have video on energy thickness?
Thanks sir aap ki video say kafi help mili nyc explanation
Sir please post video about energy thickness
Sir kindly make video on Energy thickness
Please do video on energy thickness sir
best teacher
sir when plat is not here so velocity will of element u infinity or not
sir,momentum unit is kgm/sec, nice explaination .thanks sir
Same doubt why took u instead of U infinity
Thank you sir ❤❤
Very nice sir bahoot achha sikhate hain aap thanks 👏👏
Sir aapne energy thickness ki vedio nhii bnayi...plzz imp topic ko pura cover kijiye
when there is no plate then why u return mometum =pbdyu*ui instead of p*b*dy*ui*ui where ui stream velocity
Sir...von karman..momentum integral equation...ka video lado n pls sir
Wah sir ji swad aa gaya
what is teta there ? It is really great lecture much better than my professor
Sir energy thickness bhi batyea na
Sir thanks 🙏
Sir your videos are awesome
Nice Explanation sir I got my concept clear👍
Sir pls ek video energy thickness pr bhi bna dijiye🙏🙏
Thanks sir it helps me a lot ......
Sir please explain shape factor concept
Sir please make video on three reservior problems ... exm is arriving soon if possible
Definitely
@@pavikafluidsaystawi4289 sir only five days left ....
case 2 m doubt h sir.
Bhai Energy thickness kon batayega?
Thanks sir
badhiya ho bhai
