Heat Transfer - Chapter 3 - Extended Surfaces (Fins)

In this video lecture, we discuss heat transfer from extended surfaces, or fins. Theses extended surfaces are designed to increase the rate of heat transfer (and reduce thermal resistance) by increasing the total surface area for convective heat transfer from a solid. We derive the fin equation and discuss how to solve it. We give a summary table for solutions to the fin equation (for fins of uniform cross-sectional area) under different tip conditions.

popping up the one direction meme was unexpected and cute, thanks for clear explanation >33

[@brianhansen2734]

Great lecture. Thank you :)

[@davidbrumels5911]

This was very helpful, Thank you!

[@matthewmueller8433]

I might be wrong but I think you forget to multiply cross sectional area in the conduction term at minute 10:41. Still very helpful thanks

[@artunylmaz1819]

That was amaizing. Thank you sir.

wow, I am so happy I stumbled upon your lectures.

perfect lecture
thank you from Iran

holy shit bro i was lost for a whole semester lost for half of your video then at the end everyhting clicked if i pass my final tomorrow its on you bro

[@mrrataa7882]

did u pass?

@@mrrataa7882 yes

Thank you very much

Does the heat transfer rate also follow the inverse square law; double the surface area, quadruple the heat transfer rate, all else remaining the same? Such that if a one-unit area transfers 1 watt per unit of time, then a two-unit area would give a 4 watt per unit of time transfer. Does this really work out?

Can you explain how to calculate fin depth in corrugated tank? Plz

[@prasoonsaurabh2502]

Sir area of cross-section of fin should increase or decrease it's along its length please reply

[@mysterious3994]

what does m stand for there?
is it mass?

[@doosen.]

One thing I am currently stuck on with using this table in my Heat Transfer class, is actually determining which case to use when given a problem. I understand just about everything else in this chapter besides the difference(s) in which case to use. Can someone help try and explain because I sometimes do not trust my "engineering intuition".

Great lecture, may I know the references of your topic Sir?

[@MkhuluMokoena]

by saying heat transfer is one dimension, does that mean you onlyuse one side of the fine for the heat surface area?

[@jay.jay.]

The heat transfer AREA is perpendicular to the flow of the heat. Imagine heat going through in one direction (x direction) THROUGH that surface

[@MkhuluMokoena]

@@jay.jay. meaning all the heat transfer is only transferred in the one +x direction, so does not have to double the area when working out the heat transfer.?

[@jay.jay.]

@@MkhuluMokoena yeah

[@MkhuluMokoena]

Great thanx
