Continuing the heat transfer series, in this video we take a look at conduction and the heat equation.
Fourier's law is used to calculate the rate at which heat is transferred through an object due to conduction. But it can only be applied if the temperature distribution within the body is known. To determine the temperature distribution, the heat equation needs to be solved.

rip. i fail in college engineering
you should upload regularly
I have access for CuriosityStream. But cant see your videos there ?
Where have you been for 4 months? We really missed your videos.

Finished my masters degree in Chemical Engineering and I still prefer to watch your videos for how useful they are compared to what I've been taught , thank you !
I knew that 2nd derivatives is related to concavity and convexity but I never realised it in physical problems. This gave me satisfaction, thanks for the video.
Nice..
but i think it's swapped in the video..
hill=convex, valley=concave
@@joelevi9823 that's right .... Valleys correspond to concavities. In any case, this is a very clear and educational presentation. Congratulations!!!!!!!
@@BorjaVarona_at_YT of course .. this guy videos are amazing
I was about to say that same 👍
2nd derivative is of course just the rate of change of a rate of change. Physically, the easiest example is the acceleration which is the rate of change of the velocity. Of course velocity is rate of change of position hence acceleration is 2nd derivative of position vs time.
This channel is literally the 3Blue1Brown of Engineering. You sir, are a legend.
You're channel is a gem in a world of ignorance. Thank you!
This Channel is literally helping me get through mechanics of materials TY 🙏🏾!
Endless praise for your wonderful videos. Especially how you use this video medium to improve your explanations. I specifically mean how you make animations for the equations. Usually, to explain how the equation was developed would require two blackboard filled with things crossed out and arrows pointing to terms, etc.. But you do a very good job using the medium to cleanly remove terms, make terms glide around or insert them into an equation. Really, you did a stellar job. Congrats.
I've never seen Fourier's law explained so well. Kudos!!!
Hi! I have gone down a rabbit hole of engineering triggered by my interest in musical instruments design and FEM when I found your channel. I went for a binge and I really enjoy your explanations, as an electrical/DSP engineer, it very friendly for me to catch up. After going through many of your videos, while the explanation quality was great at all points, I can tell you have improved your content greatly, for example with giving pauses for understanding what was said and mainly with switching the music to something ambient from overly joyous, rhytmical ukulele music (no extra elements that tear attention apart for ADHD folks!).
Thank you for your content, I hope you are doing well, can't wait for more!
This is so good! You are one of my favorite UA-cam educators. Thanks! Great episode as always.
Par for the course, amazing video. I'll be sharing this with my co-workers. Love the depth of the content.
This is brilliant! I majored in Chemical engineering and heat transfer always mentioned everywhere and anytime. I wish this video exist back when I took Heat Transfer 😅
I really love the way you summarize the key points and the animations! Greetings!
Amazing videos, really helps me understand the practicality of all the equations I learned in college. Keep making these amazing videos, the visuals you create are the best at helping understand the topics. I recommend if you can explain the design of the machine elements.
Thank you so much Sir...We mechanical engineers owe you a lot! Love from India ❤️
Not only the mechanicals! I'm an aerospace engineering student and I love these videos!
I'm developing a soil heat conduction model and this video has finally made the heat eq click in my head. Thanks brother 🙏🙏
Your channel is amazing, man. I'm studying Engineering and you have been extremely helpful.
Wow, this video provided such a remarkable explanation! I truly appreciate the effort and clarity that went into creating it. Thank you so much for sharing this valuable content with us. It's always a pleasure to come across videos that leave a lasting impact. Keep up the fantastic work!🥰
One of the best engineering channel
This is great help, the video goes from beginner to pro thru the timeline
👍🏻 A valuable contribution to knowledge. Helpful for every student, technician, engineer affected by the topic. Thank you.
Man pls continue with this amazing job!!! you should never stop uploading videos for us on youTube. very very helpful ❤
Very nice visual introduction to my classes about heat transfer!
Loved this one as always
This video brought back some PTSD from my university days. These problems were always a challenge for me., but you do a good job of explaining what I found to be a complicated topic. Keep up the good work.
Thanks for making this channel ...Its makes everything very simple
I love you videos ! I'm learning so much from them
Great knowledge as always. I really love it, if you work or study in Building physic will do a lot of 3 basic types of heat transfer like day in and dayout, it's very useful and interesting to learn.
Amazing work! Much appreciated
Awesome Coincidence, i'm studying about Heat.
Thanks 🙏🙇♂️
The layout of the video is excellent. Before an exam, it is beneficial.
Powerful content for a goog teaching! Congratulations for your beautiful channel and thank you for these posts 👏🏼👏🏼👏🏼👏🏼👏🏼☺️

Wonderfull UA-cam channel many thanks about this explains
It is very helpful video to me thanks
I'm also in the field of mechanical engineering
i love this channel
Damn bro, really just posted this just after my mid-sem thermo exam😢. Great video
Another great video.
Hope convection is on the way
Long wait is over 😃
Where were you when I had to pass my thermo this winter
Please make similarly great video for convection.
Excellent 👍.
PLEASE UPLOAD MORE ABOUT HEAT TRANSFER. GIVE SPECIFIC FORMULAS FOR REFLECTED, ABSORBED AND TRANSMITTED HEAT ENERGY. NEEDED FOR THESIS. THANKS A LOT. I WILL RECOMMEND YOUR VIDEOS TO MY CLASSMATES.
you are the best bro
This is beautiful
Really you are the god for me i salute u
Great video... you can make next video on eulerian vs Lagrangian in fluid mechanics
Thank god you are still alive 💐
Which god?
I have been waiting for his videos for the last couple of months, both on UA-cam and in the nebula. As there was no video, I thought he left streaming or might be ill.
But thank god he came back. His content is very insightful 😀
Hoping for consistency in his video streaming.
@@ShainAndrews Allah
@@huzaifaabedeen7119 the terrorist god? lol
your videos are so helpful, can you post a video for convection?
thank you
Thank you so much , can you please consider doing thin plate theory ?
will you be giving a video more in depth on convection? I only see radiation besides this, these videos help so much!!
Please do video on Fluid Mechanics Concepts.
SOLID MACHNICS PLAYLIST OR COURSE NEEDED
Amazing
Thank you very much😊..،I want a video of thermal conductivity analysis with convection
you are the best
Thanks Dear
can you please make about navier-stokes equations
and thank you for this fatastic video
Only one addition. At minute 12:20 you explain thermal diffusivity. You say that heat travels faster thorugh a material with higher diffusivity. However, if i understand correctly, temperature travels faster with higher diffusivity not heat.
Besides that, loved the vid!
Waiting since last 4 month for "Understanding Engineering Drawings..." video. I am on my knees...
And he did deliver
please make a video on convection and physical significance of dimensionless parameters in convection plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
I hope to share with us session about pipe stress analysis.
Hi , thanks for this usefull video.May i ask you make video about coriolis effect and gyroscopic effect.thanks you very much
Bro i love you, no way I would have passed my classes sitting in some library reading dusty ass books and riping my hair out
Your animations are very attractive so what is your software ?
And good luck.
Awesome videos, dude. Do you plan on making videos on dynamics?
Yep!
@@TheEfficientEngineer hopefully before next semester, i start my dynamics course then 😁
maybe more video for mechanics of materials ?
