Heat Transfer - Chapter 3 - Extended Surfaces (Fins)

[@dianapereo8383]

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

[@Education_vlogs_247]

Same

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

[@frito4911]

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?

[@frito4911]

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

[@hankesker912]

at 10:53 did you mean to multiply the (k dT/dx) by A_c as well? I think you may have forgotten this. Otherwise, great video. Very helpful!

[@alihosseiniroknabadi4828]

perfect lecture thank you from Iran

[@robertwhite1303]

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?

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

[@brianhansen2734]

Great lecture. Thank you :)

[@mysterious3994]

what does m stand for there? is it mass?

[@artunylmaz1819]

That was amaizing. Thank you sir.

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".

hit and trail is your best freind

[@davidbrumels5911]

This was very helpful, Thank you!

[@tusharkahar8838]

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

[@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

[@jay.jay.]

@@MkhuluMokoena you are welcome :)

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

Yes they are awesome

one direction joke was nice xD
