Heat Transfer (08): Extended surfaces (fins), fin efficiencies

0:00:15 - Review of previous lecture
0:00:30 - Purpose of fins, real-life example
0:05:22 - Derivation of temperature distribution and heat flux equations for fins
0:30:42 - Fin efficiencies

Note: This Heat Transfer lecture series (recorded in Spring 2020) will eventually replace the earlier Heat Transfer series (recorded in Fall 2015) in a couple years. The old lecture series had some errors and was lower quality.

This lecture series was recorded live at Cal Poly Pomona during Spring 2020. The textbook is "Introduction to Heat Transfer" by Bergman et al.

Camera man screwing it as always. Thank You professor Biddle for your great content anyway!

[carlosfossi]

Just wish my Heat Transfer professor was as good as Prof. Biddle. Complex problems explained in an easy way, he's just so good. Thank you CPP for providing these videos to us for free, as I would pay for Prof Biddle's lectures.

[possibilities]

Dr. Biddle uses the same textbook as my prof but explains the concepts so much better. Thank you, you are the reason I will pass my class

Update: I passed and even got a B on the finals!! THANK YOU SO MUCH

Hi!, Thanks for uploading these videos, I'm a Mechanical Engineer already, I finished my studied 2 years ago and I'm working in the Energy Gen. Industry, but...it bring warm to my heart see this course again, my prof. also was of this style of teaching, really simple, looking at difficult problems through a simple lens, seeing these videos made me remember that, thanks again for sharing, you gave a smile to my face this morning

camera man has a lot of energy, but thank you Dr. Bibble. Great teaching as always!

[abdulkadiraminu]

You are amazing. Thank you soo much for this. I have a thermo finals and honestly its all been looking like gibberish to me. Now it seems so straight forward

[alihosseiniroknabadi]

Thanks to both the cameraman and professor

[matthewramirez]

Great content, but fire that camera guy!

[olimolim]

I'm about to throw hands with the camera guy 💀

[jauvahndarville]

Love your content Dr. Biddle, but for future videos can we please find the person who recorded the fluid mechanics series 🙏🏽

[foodeater]

Old professor in my school can be hit or miss... sometimes they are great and engaging, sometimes.. uhh. I hope you stay healthy sir

[ryanking]

Where does this guy teach and why does Texas not have any professors that care about their lectures anywhere near as much as him?

[didanrahim]

Great Professor thank you. by the way "whoever wanna get a free headache watch this video no offense Mr.camera man"

[NoobAlike]

amazing lecture ruined by the camera guy.
holy moly, zoom

[mango_ace]

nice roller-coaster ride camera guy and I've got to commend you for not showing more than a single line of text for entire video. rip cpp

[priyambandyopadhyay]

hlo,
i have been following your heat transfer videos from the day of 1st lecture and i really say this is the best student friendly videos available in youtube. within 12-13 days, you have uploaded 8 lectures and i really appreciate you all.

i request you all to pls finish uploading all lectures of HT (conduction, convection, thermal radiation, heat exchangers and if any) within the month of march as i am preparing for competitive exams and i want to finish this crucial (in terms of concepts and weightage) as soon as possible.

thank you.

[niloofarabdi]

I can't believe how he could learn such this amazing way and easy to understand, good for his students....🤩🤩

[amoolekan]

Please what textbook are the questions from?

[orianabelandriaquintero]

Hi, I have been studying heat transfer in fins and I have seen that sometimes they use m (to calculate efficiency or heat) as
m= (h×P/K×Ac)^1/2 and sometimes as
m= (2×h/K×t)^1/2
Could someone help me to understand when to use one or the other?

[federico]

To find Ac, the area of conduction, i didn't understand why the perimeter and dx are multiplied. Shouldn't it be the area inside the perimeter?
