Heat Transfer (07): Overall heat transfer coefficient, composite geometries examples

[@mikhailfong6234]

What a gem of a Professor. Crystal clear and precise. You guys are/were so fortunate to have him. Salute and respect to Professor Biddle. Malaysia

[@CPPMechEngTutorials]

Thanks!

[@alazharalhadrami9137]

I totally agree with you? couldn't get better doctor or professor to explain this well

[@_MITALIDIWEKAR]

I wish I had a professor like you in my uni. Literally a gem!

[@danielzhao8340]

it's been a long time to see Professor Biddle again! love his fluid mechanics class

Professor Biddle is a real motha fucka, he has saved me this quarter

[@vicentereiman368]

The greatest professor on the internet! Thank you so much sir!!!

[@muhammadsaadsarfraz9915]

now i think this subject is interesting thanks professor

[@sanjitpandey552]

Are you sure the cameraman getting paid? I don't think so.

[@devrajgoswami4357]

Everything good awesome teaching good video n sound quality but the cameraman :"wait lemme use this cool function called zoom"

[@dinushachathuranga7657]

Buch of thanks for crystal clear explanations.❤❤❤

[@thetahirss]

I think, Lins/Kins is equals to 1.087 18:40

[@barcorn6991]

finding the temperature isn't the denominator of the thermal resistance of the cylinder suppose to be 2piK?

[@shreddingstranger]

Yes

[@mohammedalzaabi2969]

I think yes

[@edanurkose5942]

thats because we use diameter, not radius

[@orlandocanada2738]

hello sir thankyou for uploading informative videos,

[@oneofyk]

were the r1 and r2 values given in the last question? cant seem to find where if the proff mentions them

[@barcorn6991]

it is given in the question r2=40mm and r1=20mm

[@EvaIungbliudt]

Super clear!!! Huge thanks

[@kostiak1294]

The only thing I don't get in the last example is why A=Pi*D, if circle area equals A=Pi*r^2?

[@kapils7904]

The area is the surface area which is A= Pi * D * L, and in the last example, he has solved q', which means he divided by L, hence Pi*D. One step was skipped in between Hope this helps!

[@kostiak1294]

@@kapils7904 Thanks a lot!

[@xplosiveactionarchive9092]

What is the difference between Ui and Uo equation wise? Would Uo be the full 1/denominator and Ui be 1/conv(inside)+cond(through) or just 1/conv(inside) ?

[@morfinview]

Absolutely wonderful ❤

[@AquaponicsEngineer]

So how do you get "h" value for air at temperature 5 C or 25 C. ext. Thanks..

[@haliomar1]

genous

[@abahomark290]

what's are the values for the first question. i seem to be getting a different answer

[@TheKiwi0201]

I'm curious that how can I exactly calculate h_air ?

[@theogreen2186]

It’s a table value !

[@zaccolyer3053]

any chance you cover topics for fluids 2

[@mohammadqasim7773]

What a gem ❤️

[@CPPMechEngTutorials]

He sure is.

[@princezachariah4893]

thank you professor

[@sreeharisureshbabu268]

Thank you prof!💮

[@Zoom8188-ee1hq]

well for the rod problem, someone forgot to give us the values for r1 and r2 as well as the K lol

[@barcorn6991]

P3.52). is it not suppose to be 251 W/m

[@abahomark290]

how do you get D?

[@berkecakr3467]

Great !

[@drscott1]

👍🏼

[@CPPMechEngTutorials]

👍🏼

[@alazharalhadrami9137]

Can you please give us the homework as well ? so we can solve them too :(

[@CPPMechEngTutorials]

The syllabi are at this website: www.cpp.edu/meonline/heat-transfer.shtml

[@emir2591]

legend

[@CPPMechEngTutorials]

He sure is.

[@falconplayz923]

which text book he is using for this course? kindly mention auther's name and volume of the book too

[@Mmichel07]

I'm guessing, "introduction to heat transfer, 6th ed" bergman, T.L et. al, published by wiley

[@hemre1913]

what a dump cameraman :''/

[@berkestudent9877]

Great !
