Fluid Mechanics: Dimensional Analysis (23 of 34)

[@siddhartharaja9413]

Respect to such professors,who goes into the reasoning of everything which they teaches instead of solving numericals with clumsy equations.!love from india sir!!

[@CPPMechEngTutorials]

Thanks!

[@zaiddyers8283]

grate stuff professor.i like your passion for the subject

[@gloam1105]

I agree. Thanks Professor Biddle, I watched your lectures to get through my fluids course.

[@jumpanama]

Imagine having a professor as awesome as this guy...

[@iainshevlin9333]

I did!

[@leminhduy8368]

I was in a chemical engineering school 5 years ago and trust me, this introduction of dimensional analysic is a masterpiece. Thanks so much for this lecture!

[@CPPMechEngTutorials]

He sure loves his dimensional analysis.

[@wertzuio2127]

The prof is an absolute god-sent. My prof just rushed through the process and what to do, without once going into "why" we even do this. Props from Germany

[@nanodynamics5203]

Those 15 minutes in the beginning of the lecture worths millions of dollars. Thanks professor. It would be helpful if those notes are available online

[@divyanshuraj4085]

I am really very thankful to the PROFESSOR , and the TEAM that turned it to us !! SUCH PROFESSORS are very rare from where i belong !! I WISH I COULD NURTURE MY SELF IN SUCH ENVIRONMENT CREATED BY TEACHERS LIKE YOU !!!

[@CPPMechEngTutorials]

THANKS!

[@bijoydeori4469]

can i see those lectures for preprtion for gate??

[@belisariogonzalez7793]

this guy is the best hands down. He accomplishes what many professors try so hard to accomplish...

The amount of clarity from this lecture is simply mind-blowing

[@kiddjmadd]

Hands down the best explanation of the Pi theorem I've seen (though granted, I may have skipped that class or not realized the importance / paid attention back in college). Apparently, nature doesn't care about our arbitrary, man-made units. Thanks so much Professor!

I tried watching this to fall asleep, it didn't work. I hope you're proud of yourself. Great teaching, well done.

Why not watch a second time?

[@kkguptahp]

Iam learning FM from you now at 64 and applying in profession thanks professor

[@darrenpoh955]

Professor Biddle is phenomenal. His teaching makes me more keen in learning fluid mechanics than ever

[@CPPMechEngTutorials]

That's why we recorded him. :)

[@Peter_1986]

Professor Biddle has perfect ratings on "Rate My Professors"; they literally cannot get any better.

[@creativegamer5120]

I like that, the way of teaching of this professor is amazing and reasonable. I like this video, and I suggest my friends watch this video and gain knowledge.

[@henrytenecela6629]

Glad the student asked the question about why he didn't choose FD or u as repeating variables. Kudos to you!

what a great lecture. Thank you for showing all the cases as well. nicely done as always professor Biddle

Things that I can't understand in my class, this professor explained perfectly. I wish I can attend his class in real life. Why did I just figure out this channel?

Hope you enjoy the rest of the channel!

You're the best Dr Biddle!

[@hugoscoviske]

Very good class! John Biddle is the man!

[@asdfghjklmayraa]

my question is, why did we use the radius as a variable instead of the length of the cylinder? could we have used either?

[@arseniikvachan1309]

Yes, you can. It is dimensional analysis. It is an approximation on the output, given a relative input. This is not nuclear physics or something. But the best option will be probably to use the volume.

John Biddle where have you been all my life? 🤔 I have watched countless engineering related videos and just happened to stumble into this one. 🥳 Thank you very much and is there a text book? PS our engineers pick up the phone and talk to sales people. Sometimes it even works. 🤣

[@CPPMechEngTutorials]

Good professors such as John Biddle make you feel like they are talking to you; bad professors make you feel like they are talking to themselves.

[@amanda2276]

Thank you!!! way better than my lecture

[@Oxone_2KHSO5]

Given the roughness, is it possible to solve the problem using only 2 pi? The roughness would be a repeating variable.

[@MATHSdotPHYSICS]

Great lecture. Respect 👏

[@androidbeginners3043]

I would buy a ticket for this lecture ❤️

[@evazhang3232]

Thank you for the lecture! I am wondering how to determine the very first step. how to determine FD is a function of D V rho and miu. if we are in the process of research, we don't know what really matters to this force. maybe we can list few, but i am not sure if we can list all. Does this method works if I miss one of the parameter, for example, I didn't recognize miu. so FD is just a function of DV rho. or someone also mention T, if T is part of the FD function, what then? does this method work in an uncertain condition? or maybe the graph we plot at the end will tell if we found all and reasonable correct parameter? Thank you!

[@MisterBinx]

My only question is why did you select 3 dimensionless parameters instead of 4. I know you have two pi terms and add on the remaining parameters but there is no mention of how many you should select. Just that they need to have m,L, and t.

[@Mullligan]

The number of repeating variables you use is also m, which is the number of primary dimensions (M, L, T) present. The number of repeating variables you choose can also be less than m if m amount is not possible, eg if some of the variables are dimensionless.

Why length of the cylinder is not considered as a variable? or why drag force is not a function of length of cylinder?

Could anyone walk me through how to do this for Mach number in a turbo machine? I am so lost in my thermo class trying to use this method.

Is that U* called U+? Afaik U* is friction velocity and it isn't dimensionless. I'm slightly confused or maybe he's just using a different notation.

pi should be dimensionless but in the last example the pi the you find is v/hu which is not dimensionless.
