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!
I feel nauseous just watching it lol.
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.
We are now accepting Venmo. (just kidding)
@@CPPMechEngTutorials Drop a link, will trade for more content
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
Good luck!
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!
Great content, but fire that camera guy!
I'm about to throw hands with the camera guy 💀
Thanks to both the cameraman and professor
this camera guy drives me crazy -.-
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
Great Professor thank you. by the way "whoever wanna get a free headache watch this video no offense Mr.camera man"
Where does this guy teach and why does Texas not have any professors that care about their lectures anywhere near as much as him?
Old professor in my school can be hit or miss... sometimes they are great and engaging, sometimes.. uhh. I hope you stay healthy sir
amazing professor,
Thank you Professor 🙏
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
We now have an updated lecture series from 2020.
Just loved it..
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?
Love your content Dr. Biddle, but for future videos can we please find the person who recorded the fluid mechanics series 🙏🏽
he/she is welknown cameraman in indian serie society
amazing lecture ruined by the camera guy.
holy moly, zoom outtttt
How to estimate the one side insulated fin?
thanks so much ❤
I can't believe how he could learn such this amazing way and easy to understand, good for his students....🤩🤩
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.
You can check out an earlier version of the series here: ua-cam.com/play/PLZOZfX_TaWAE6nTX50dJl0Jia8iQTIhrG.html
Please what textbook are the questions from?
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?
area inside the perimeter is not exposed. the surface along the area is exposed and for differential element its length is dx.
Great

mL≥5 for infinite long fin
Camera man needs a new job. Lol
28:30
Kameraman çok sağlam ana bacı sövdüm sana, helal et
Adama kafayı yedirtiyor 💀 ama Abid Ustaoğlu videolarindaki kadar kötü değil.
Hey camera man, if you dont like the job, leave it. Why do you screw good lectures of professor? screwing one lecture is fine, I am pissed to the core that you do the same for all lectures. AH
