📝 Summary of Key Points: 📌 The velocity profile in fluid mechanics refers to the unique type of velocity experienced by a fluid flowing through a pipe. The fluid particles come to a stop at the surface of the pipe due to the no slip condition caused by viscosity. 🧐 The boundary layer is the flow region adjacent to the wall where viscous effects are significant. In this region, the fluid layers slow down due to viscous forces, creating a layer that sticks to the surface. Away from the boundary layer, the velocity remains constant in the radial direction, creating the rotational flow region. 🚀 The thickness of the boundary layer increases in the flow direction until it fills the entire pipe. The region from the pipe inlet to the point where the velocity profile is fully developed is called the hydrodynamic entrance region, and the length of this region is known as the hydrodynamic entry length. 🚀 The velocity profile varies along the radius of the pipe. At the center of the pipe, the velocity is maximum, while at the complete radius of the pipe, the velocity is zero due to the no slip condition. The velocity profile is parabolic in laminar flow and flatter or fuller in turbulent flow. 🚀 Understanding the velocity profile is important for fluid mechanics calculations as it simplifies calculations by depending only on the pipe radius. 💡 Additional Insights and Observations: 💬 "The no slip condition is caused by viscosity, which is the fluid property responsible for the development of the boundary layer." 📊 No specific data or statistics were mentioned in the video. 🌐 No specific references or sources were mentioned in the video. 📣 Concluding Remarks: The velocity profile in fluid mechanics is a crucial concept to understand when studying the flow of fluids through pipes. It is influenced by the no slip condition, viscosity, and the development of the boundary layer. By understanding the velocity profile, engineers and scientists can simplify calculations and make accurate predictions about fluid behavior in various applications. Made by Talkbud
It just means velocity is function of pipe length .. velocity varies throughout the length of pipe ... well if the pipe is good, water flows faster and if it is clogged the flow velocity is reduced.
Crystal clear concepts, If there is no energy loss in the fluid along hydrodynamic entry length , the velocity vector at the centre of the pipe will increase as the velocity vectors at the boundary of the pipe decrease. This is due to law of conservation of linear momentum 😘😘😘.
Thanks a lot for such an amazing vedio❤️ Can u please help me with the meaning of "turbulent velocity profile is fuller than laminar one". Its connected with the shape or form factor. What does it exactly mean? Thanks in advance.

I'm preparing the long question of no-slip condition for my mids exams at 1:58AM
So interesting and amazing
plenty of thanks
Crystal clear
Awesome work 💪👏👏
Thank you friend :)
Your videos are easy to understand Bro
Thanking you bro...
Welcome my dear friend ^.^
What do you mean when you say velocity is a function of pipeline?
It just means velocity is function of pipe length .. velocity varies throughout the length of pipe ... well if the pipe is good, water flows faster and if it is clogged the flow velocity is reduced.
It was great explanation ...thanks a lot
just subscribed
Thank you Ma'am for your valuable and excellent expalanation. It really helped me and got my concepts cleared. 🍫
Please#KEEP UP THE GOOD WORK !!! 😄👍💐
Great content 😌
Is there any way to reduce this boundary layer by changing the surface of the entry of the pipe?
Thanks for this explanation, please be kind enough to upload a video based on the pitot-static tube.
Hey it's here th-cam.com/video/3zEdtkuNYLU/w-d-xo.html ... ^^

Great video thank you so much
More of this please 👍🏿
what software do you use fr creating the 3d motion and graphics
Blender ofcourse
Awesome animation 🔥🔥
Isse assan tarika ni ho sakta. Thanks
Thank you /\
Thanks

Grt
Very interesting video. In which software do you build this animation??
Thank you so much 💓
very much useful, thanks
thank you so much
Thanks a lot
Thankyou ❤️❤️❤️
Thanks !
I missed a ''Oh, look!'' in this one...
Good video 😊,pls make playlist of remaining maths videos
Yeah I am Working on it ^^
Thanks too much
amazing
amazing!
Thx bro ^^
Thank you!
wlc ^^
your hydrodynamic length is wrong. it should end at the cusp.
humm ... will take a look. right now busy on my work ^^
