absolutely love these lectures!!! probably the best I've ever understood a topic from an ME Professor!

[omido]

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.

Dr Biddle is a god among mere professors. Single-handedly saving my bacon this term!! Thank you x 1, 000, 000!

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.

[batuhankaya]

in the first question why did we use Lc (5.25) instead of L(5) when we solve by Fig 3.19?

Camera man might be sleeping during this class

[ennzor]

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...

[ziwenhe]

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

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.

[jhfghrt]

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?

Wonderful Heat Transfer lectures ! ! !

[soulseeker]

great lecture, but the camera man was no good. too slow turning the camera and following the professor.

[muzahedsir]

What is the name of this text book that has used?

[j.halak]

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.

The science get so deep even an alien open YouTube and start to learn 17:44 it's not funny i know
