Euler's Equation for Motion and Bernoulli's Theorem | video in HINDI | EduPoint
In this physics video in Hindi we derived the Euler's equation for motion in fluid mechanics and from this formula we derived Bernoulli's equation in fluid mechanics. The Euler's equation for steady flow of an ideal fluid along a streamline is a relation between the velocity, pressure and density of a moving fluid. It is based on the Newton's Second Law of Motion. The integration of the equation gives Bernoulli's equation in the form of energy per unit weight of the following fluid.
It is based on the following assumptions:
(1) The fluid is non-viscous (i,e., the frictional losses are zero).
(2) The fluid is homogeneous and incompressible (i.e., mass density of the fluid is constant).
(3) The flow is continuous, steady and along the streamline.
(4) The velocity of the flow is uniform over the section.
(5) No energy or force (except gravity and pressure forces) is involved in the flow.
In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.

@@edupoint.physics Net applied force ( -dpdA) negative kyu aaraha hai ??? apne upper side force ( p + dp ) kyu kiya upar mein kya pressure zada hoga? please clear my doubt ❤
With very basic explanation of fundamentals, Crisp and Clean Content. 10/10 🙌
I wish there was a button for SUPER LIKE in KZread..... 👍❤️
love u sirr from the bottom of my heart aapne kal fluids k paper m jaan bcha li

Best teacher ever ....it so sad he underrated ..... support him so that he can keep on helping students in so simplified way ❤️❤️❤️❤️
Sir I want to thank you by the bottom of my heart ❤️❤️❤️ for your effort.... Your are one of the best teachers in my life.....
Better way of teaching..... Very good sir
extremely well... thanks for clear concept
P +dp is more than p then how fluid will move in upward direction and mg cos©is also added in p+dp
You're Great sir... Respect From South India❤️
a great helping hands to students for easy learning.thank u so much,sir

Great sir ji
Mazaa aa gaya, thanks a lot.
Great teachers i have seen
Thank you so much sir..
With due respect your work is very great sir but this is all we have studied in our books. If you are making a video then kindly explain the 'Why' in the things. Like you said here pressure is this then please explain why is pressure P on one side and P+dp on other. Thanks
Thanks sir very helpfull video
Great sir. Well explained
extremely helpfull lecture.keep supporting us.and thank you sir for nice lecture
Bahut achha samjhaye sir aap
Sir you are great.....
Really amazing explanation 🌸✌️
Thanks for making 2 hours worthy in 15 minutes
Sir your teaching method is very clear
Awesome explanation 👌
Thanks sir for your video.it's really helpful
Thank you sir nice video
Sir can you tell me what would be eulers equation for non steady flow of non viscous and incompressible fluid through the tube ?
Thank u sir for such a awesome derivation 👍👍
Powerful explanation sir🙏🙏
Superb explain sir....
Bahut hi achha explain Kiya sir bahut hi samjh me aaya thank you sir

wao sir nice explanation
Nice video sir, i get it in 2 min.
Super ... vedio
nice explanation
Thanks❤ Sirr
THANK YOU SIR
after watching yr vedios ,,,,,,,Kitna saral kitna easy hai sabkuch। Isbar faaaad dunga 😄
Wow sir thank you so much..Apne itni achhe se samjhaya ki Koi v dull bachha v samjh jaye.. Dislike jisne kiya.. Wo dull se v dull hoga..
Sir mgsintheta ka effect kyu nhi pdega voh 90 ka angle bna rha h toh sin 90 toh 1 hota h
sir can u plz upload the eulers equation in 3 D flow
good lecture
Who will balance mgsin@ and how this pressure develop if you tell me my dout will be clear .
amazing
sir State and prove Bernoulli’s principle for the flow of non-viscous fluid and Bernoulli’s principle for the flow of viscous fluid m koi difference h kya viscous and non viscous
Thanks
I owe you for the great video......

Water flows from higher pressure zone to lower pressure zone ..then how the fluid will be flow in s direction?
Sir aap ek Buckingham pi theorm bhi please ek video bnao and thanku for this video its very easy to learn.
F=ma is directly applicable to solid mass only. Because as per newton's formula force is rate of change of linear momentum. In solid, mass is fixed so we can write F=ma but for liquid it is not like that.
