absolutely love these lectures!!! probably the best I've ever understood a topic from an ME Professor!
I love all of your lectures professor. I wish we had you teaching at our university. Thank you for posting these videos. They are extremely life saving.
My biggest mistake was taking this class in 6 weeks with a terrible professor. Thank you for replacing him.
BU ADAM BİR HARİKA DOSTİM
Thanks!
Dr Biddle is a god among mere professors. Single-handedly saving my bacon this term!! Thank you x 1,000,000!
Camera man might be sleeping during this class
Jeez!!!
At 31:54 when calculating Af, why are the surface area of the sides of the fin not considered? Only the top and bottom was considered...
because the length "w" was infinitely long
As he said in the lecture it is wide and long fin, but I think we can add that it is very small compared to the top and bottom.
Watch min 36:30
in the first question why did we use Lc (5.25) instead of L(5) when we solve by Fig 3.19?
pretty late but i hope it helps. the question mentions convection from the tip and while solving for fins with convective tips we tend to account for the heat losses from the convective tip by assuming an insulated tip with an extended (i.e corrected length). if my explanation isn't as clear you can check this where he explains the same (in the second half of the video) ua-cam.com/video/I-xbn0kw8GA/v-deo.html
Wonderful Heat Transfer lectures ! ! !
Can someone help me out? why the professor add the side area around 19:00 ? but the equation in the book is just Af=Lc*t
isnt Lc*t suppose to be Ap ?
This lessons are wonderful. But i got 2 questions. Why we used sinh and cosh formula instead of using M*tanh(mL) in first question? And is it M*tanh(mLc) for convection at the fin tip? Cause i tried it with Lc and find the correct answer. Thanks for the proferssor and his crew.
It will be the same if u use tanh and for the second question,no it's not for the tip because we neglect ∆t of the tip cause it's almost zero but it's for the base hope u understood
Phenomenal prof
Hey at 28:43 , can someone tell me how he get 0.077? and the K still 180 right? if so, i got 0.0894.
The value of K aluminium is 237.75 at 250 deg C using the value given in the appendix of the book that Prof. Biddle is using, and the value would be .077
@@byagnik I see. Thank you so much!!!
great lecture, but the camera man was no good. too slow turning the camera and following the professor.
It was a tricky filming in this narrow room.
still a great lecture and very helpful, you guys literally saved my grade. I have a midterm this Thursday for my heat transfer class and could not wrap my head around anything but after watching these videos, I think I got 95% of what I need to know down. I just got impatient when he would go to point out where he got stuff, like the area of a particular drawing, but the camera would not veer there and its something that I wanted to know, little things like that. Overall though, I am very grateful for these video lectures, Dr.Biddle is a million times better than my professor, you guys are lucky. Thank you very much for taking the time to film and post them :)
We're glad it helped. :)
CPPMechEngTutorials you folks should also do some chemical engineering lectures too. It's so refreshing finding someone actually teach material and show you every detail, instead of reading off a power point and than talk about their research & advertisement for grad school & not speak clearly. I go to a UC & let me just say the learning is terrible. U guys do an amazing job teaching these complicated concepts and the hands on learning is the best way. I regret not choosing you folks, because I literally go to your channel instead of my real life lectures.
We appreciate the compliment. There are pros and cons to each type of university. UCs offer some of the best research opportunities in the world, while CSUs allow you to have more personal interaction with instructors -- at CPP, faculty offices are in the same hallways as classrooms and ME class sizes are ~30 students.
At the moment, the ME department is focused on creating materials for ME courses (just working on ME content takes a lot of time). However, we are interested in working with other departments at CPP in the long term.
hello! just wondering the range of acceptable answer for the fins problem when solving via equation and by graphical method. Let suppose i solve the problem ans i get q=4.4562 watt when solving via equation, and 4.58 watt when solving via the efficiency graph. is this differences is within the acceptable range?
can you give me a Tutorials about the subject
16:41 how did he found 0.83?
what the name of the book he used
Introduction to Heat Transfer, Sixth Edition by Theodore L. Bergman, Adrienne S. Lavine, David P. DeWitt, Frank P. Incropera
@@byagnik can i have a copy of the book ?
@@fatimaal-zahraa5016 zlibrary
What is the name of this text book that has used?
Frank p incropera
@@siddhartharaja9413 thanks
anyone in 2024 come here
Very fast camera man bro like folivora.........
Nice
What textbook is used?
Fundamentals of Mass and Heat Transfer by Bergman. Looks like the 7th edition.
The science get so deep even an alien open UA-cam and start to learn 17:44 it's not funny i know
The camera person is doing a bad job, always late and slow to move the camera across. I recommend you find someone else to re-film these lectures if possible because important information is being missed. I watched Thermo 2 by prof Miller and the camera person was better than the one filming these HT lectures.
