Buckingham Pi Theorem Application

[nathandyson]

Probably the 20th clip I've watched on B-pi Theorem and the only one that has made sense to me

[nashbatten]

I've been in college for over 3 years and this is the best professor i've ever had. Thank you for the past 8 minutes of my life.

[nezha]

I just want to thank you from the bottom of my heart for this clear explanation!Thank you.

[lisandroluzzi]

thank you so much for this video. literally searched everywhere for an explanation for this theorem and this is the only video that has helped me

mechanical engineering student here
it was brilliant!

[CristianLopez-gwrx]

Your video is really clear. I have seen lot of videos about this topic, but most of them are confusing. Congrats for your method.

You are correct that we are plotting Re on the x-axis and we defined this earlier as Pi1'.

[LearnChemE]

You choose the same number as reference dimensions (i.e. length, time, mass).

[Jan_Heckmann]

Extremly interesting and good explained!
Even as a somebody who doesnt speak English as native Language I got it all!

Hi there! How does one choose the repeating variables? What defines a repeating variable? I seem to follow the rest of the operation well but I've looked in many places and have not been able to understand how the repeating variables are identified and chosen. Thank you!

Why isnt pi 2 prime the inverse of pi 2, like pi 1 prime?

[syafiqshaikh]

really helping for my final exam fluid
you are the bestt -utm-

[jenniferbetley]

Best tutorial for dimensional analysis out there! Thanks!

[abernish]

This helped refresh me on the material for an exam. Thank you!

[scooner]

pi 1 is the reciprocal of the Reynolds number, right? feel like that should be pi 1 prime at the end, but i may be wrong

[lethukuthulavilakazi]

That makes sense, but I get stuck as to how do I now use these Pi terms to my benefit? How do I end up plotting? Which values were used in the plot as these Pi terms still include a number of variables.

[naumanriyazmaldar]

Why didn't you choose dynamic viscosity as a repeating variable? and why did you choose the other three?

[vamsikrishna]

how do we choose the repeating variables???

[collegecheme]

As stated, step 1 is rather confusing. Were the variables chosen arbitrarily? Why were those variables chosen? Why not take others into consideration for instance the pressure or acceleration of the sphere? Wouldn't those affect the drag coefficient?

I'm not even english but this is saving my chem semester
