You are a god... you have the best explanation for buckingham pi theorem on Youtube.

[AAG]

Finally a method that is repeatable and doesn't have gaping holes in logic and knowledge. Top job!

[youssefomran]

You just don't understand how helpful this was for me, Appreciate that clean simple explanation.

[willFALL]

went through 3 vids on Buckingham Pi, this is by far the best one! thank you!

[HitlistTheDJ]

Definitely the best explanation on Youtube

[andilenjani]

wow i never thought i had the cognitive ability for dimensional analysis, thank you very much

[paulbester]

Holy cheesecakes man! You saved my skin. Writing test on this subject soon, put me squarely on the right track.

[ECLIPSIFY]

Great explanation! All the doubts that I had during my class are gone. Thanks for the video!

[rashedb]

pls keep up with teaching and providing tutorials cuz you are, with no doubt, talented.

[VibudaJayathilake]

The explanation is superb, but I think there is a small mistake in the general repeater variable list because when we choose the variables for fluid mechanics we have to choose;

1. A geometric property (eg:- Length, height etc.)
2. A flow property (Velocity, angular velocity etc.)
3. A fluid property (Kinematic viscosity, Dynamic viscosity, density etc.)

But in the 2nd point of the "general repeater variables" in your list you have selected a geometric property and TWO fluid properties (density and viscosity), which will give an erroneous answer!

Correct me if I'm wrong! Thank you! Nevertheless great explanation! Hats off!

Thanks, homie! You made this a lot easier!!

[ezzablejohn]

I love the way you explain the methods to solve the problem but I still dont understand how to choose the repeating and non-repeating variables

[truckynforky]

THANK YOU! Best explanation ever, God Bless!

[muhammadsaid]

thank you so much, your explanation was phenomenal

[denizdemirbogan]

Your channel deserve better! Gracias Amigooo!!

[cloudy]

Thank you so much, you saved my life ❤️

[binyamgezahegn]

Thank you. it was a good lecture. But i have a question please. Is there any possible way to have pi groups with repeating variables more than the no of the fundamental independent variables?

[monkeypolicd]

why not u(viscosity) as your repeated variable?

[ricardoalexandrem.santos]

Thanks for the video... I want to ask if for a function F which contains parameters with no units (ex: Poisson's ratio, friction angle, etc) and knowing these have a great influence on the parameter on the left-side of the equation, will it follow the same procedure?

[Sofia-jple]

So I tried solving this on my own and for some reason I get the ρDV/μ instead of the inverse which was the answer in the video. Anyone have any idea what I might be doing wrong?
