On the last part where you said velocity inside the boundary layer is 0.8115*U, is that the x-component only of the inside BL's velocity or is it the magnitude? Does the inner BL velocity have a y-component? Thank you so much for these videos!
Thanks for the great video's! I use the video's on Khan Academy to learn math, but there's no fluid dynamics-playlist there. Your style is very similar to that on Khan Academy. Maybe you can collaborate with Khan and share your video's on his site too. Thank you!
That's exactly what I've been searching for for hours now. Everybody talks about the flat plate analogy but in a pipe, I think the length x (in the direction of the flow) is not relevant. There will be a boundary layer with the same thickness after 10 m as after 1000 m in the pipe and it's the thickness of that layer I would like to calculate, both for laminar and turbulent flow.
Got an exam tomorrow. This clarified everything. thanks a lot
Hope your exam went well
Cleared up a basic concept for me. Thank you so much
Thank you ! You are a really good teacher.
very good overview and recap, thanks

Thank you so much for these videos!
It is magnitude of Velocity component Parallel to the solid boundary. It cannot have a normal component.
is it worth mentioning that the velocity profiles you have drawn are time averaged?
Well explained!!

@ 4:26 Why does the boundary take a jump in turbulent region? What exactly happens in that region?
Can u give details about displacement boundary layer thickness in laminar pipe flow.....reply asap

so useful, thanks
is Blasuis Solution applied for other solids or just in the case of flat plat ?
The Blasius solution was for boundary layers that develop on a semi-infinite flat plate.
thank you
Cool!
superb
tq
Thanx :-)
can u show how to determinate the thickness in turbulent flow?
