What is the effect of Cross Sectional Area on Pressure and Velocity in a pipe? | Interview Questions 

watched a lot of videos out there to clear my doubts but this video clealred all my doubts and thankyou mate for wonderful explanation.

Amazing explanation! Thank you so much

great thanks for clearing the pressure doubts .... at the end

Really explained so well...thank u so much fr such a good video Make more 👍

delivered good concept

Nicely explained Bro👌...can you please tell me which book did you refered for this concept????

Best ever explained!

thank you

Great work

sir i have one doubt, while deriving the bernoulli's eqn we used workdone which is F*D , where F is replaced by pressure * area , this is the pressure which comes in final equation. then how come this pressure is different and hydrostatic pressure is different ?..............in bernoulli's eqn pressure acting on pipe wall is not considered, then how you use that to explain??

Nice

What happened about Q???

but what when the pipe is uniform?velocity chages on sections or not?

This is all assuming you have adequate flow rate to keep the cavity full of fluid at all times? E.g. doesnt this break down when you go from a cross section to a relatively absurd cross section. For example when fluid leaves a hose into the environment. The pressure clearly does not increase, yes?

Is this applicable for airflow??

🎉🎉🎉

First go and clear concept ,that pressure is not on wall...what u say??

Or you could just say it as pressure in the fluid and pressure exerted by the fluid 😉

Don't choke when you talk
