Fluid Mechanics: Topic 10.3 - Steamlines, streaklines, and pathlines

[@sammy72385]

Thank you for being so clear and giving examples I can understand. I'm not the brightest bulb but I'm trying. This helps tremendously with my understanding now. 🙏🙏🙏

[@akashrai2524]

This is the perfect theoretical explanation of this topic

[@vatssagar9022]

The Best explanation, the way and the ease he demonstrated pathline and streakline is extraordinary. Thankyou!

[@MostafaMahmoud-wz6gx]

Wow, a perfect and creative explanation I have ever seen

[@CPPMechEngTutorials]

Thanks! Happy holidays!

i appreciate so much this video, when i read the Fox was so difficult to understand all this concepts but with this video i learned them.

[@filipeguimaraes2843]

Exactly what happened to me. Fox did mess up explaining these concepts.

[@ZubairKhanFIghter]

after million of hours i have got my desired video

[@CPPMechEngTutorials]

But the average person lives less than 1 million hours.

Just got a 100 on my aero quiz; thanks for the help!

[@CPPMechEngTutorials]

100 on an aero quiz for $100? jkjk

[@yigitcan824]

I have a question here Professors. The streamlines are _parallel_ or _tangent_ to the velocity vector? I saw some source saying different things. Which one is correct?
I really appreciate it

[@CPPMechEngTutorials]

Velocity vectors are tangent to the streamlines. If there is uniform flow, then tangent and parallel is the same thing.

Oh got that I have another question about 1D,2D and 3D flow.Let's say our velocity field is V=(4x)i+(5y)j-(8xy)k , I saw that the flow here is 2D.However,ı don't understand how's that possible? It2s 3 dimensional coordinate system but 2D flow?
I'd be grateful if you could answer me here.

[@CPPMechEngTutorials]

@@yigitcan824 Unfortunately, we don't have the bandwidth to respond to every question. The flow depicted in the video is 2D, but the same principles apply to 3D flow.

[@za6551]

why is the lower case (u) necessarily in the x axis can it be on the y axis

[@CPPMechEngTutorials]

Can you provide a timestamp?

[@JallerStrife]

Are the stream lines tangent to the direction field or the velocity field? Or are they the same?

[@akashrai2524]

They are the same, cuz velocity also has direction.

Dude tomorrow is my Mid-sem and i just started fluid mechanics 🐸

[@CPPMechEngTutorials]

Dude... you might be in trouble. :D

thank you

[@sahilguleria4979]

Thnx bro that was neat and clean explanation 🤟

[@youeclipseall]

Thank you for making this

[@CPPMechEngTutorials]

Thank you for watching. :)

Thanks a lot. A perfect explanation it is.

[@CPPMechEngTutorials]

Glad it was helpful.

[@grideffect1193]

Thank you.

[@CPPMechEngTutorials]

Our pleasure.

[@zainullah2090]

Nice explanation

[@CPPMechEngTutorials]

Thanks!

[@gn02250761]

Thank you so much

[@CPPMechEngTutorials]

Sure, no problem.

[@jay22kar]

Great fucking example!

[@CPPMechEngTutorials]

Hooray!
