Thanks for watching - let me know what you think! And don't forget to check out the companion video on thermal resistance by signing up for the Nebula - nebula.tv/videos/the-efficient-engineer-understanding-thermal-resistance.
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.
@@joelevi9823 that's right .... Valleys correspond to concavities. In any case, this is a very clear and educational presentation. Congratulations!!!!!!!
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.
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.
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 😅
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.
i had to stop watching to Comment, you guys really made an amazing Job simplifying such complex topics, in those 20 minutes; it takes many chapter to go through all this, really really good work here .
You can't imagine how useful this channel for me, thank you for that Can you please make videos about fluid mechanics topics especialy navier stokes equations
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.
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.
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.
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!
I have been waiting for his videos for the last couple of months, both on TH-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.
I would even say that the resonant harmonic oscillations of charged particles within a gradient field that interacts with said charged particles is energy stored within the electromagnetic, dimensionally finite field - kinetic energy, or heat as we like to say. Due to the "bonds" ... which is the relative positive or negative directional attraction of charged particles due to a non-uniform gradient field coupled with attractive and repulsive forces due to the particle's inherent charges, each particle containing a non-uniform gradient field in itself (U = Eds), within a dimensionally finite system - the "energy" or "heat" is being "forced" to move across gradients to dimensionally local finite points of low harmonic oscillations. The question one has to pose is always: how fine do I set my relative scale? The universe is literally an infinite amount of dimensionally finite subsystems; a system is defined as a dimensionally finite region within its dimensions that has the same relative permeability with the ability to store energy within its momentum (dimensionally moved charged particles within a non-uniform gradient field) as well as convert energy by dimensional displacement against a relative positive attraction within a non-uniform gradient field, in physics it is called work. W = Fds.
Bro how u memories this much technical content.... I read but can't understand.... How u wrote this much technical... What are things I need to do to write like u.... Pls give some tips
@@srinivasanv6573 I think a lot about how to explain the world with just electromagnetism - like Nikola Tesla said: "If you want to find the secrets of the Universe, think in terms of energy, frequency and vibration".
@@srinivasanv6573 Currently I am reading Appassionata by Alfred Amenda, a life novel about Ludwig van Beethoven. My best advice is to, no matter what you do, always try to learn something new and stop doing the same things every day. I hope you have a great life and maybe we will meet someday. All the best, cheers!
Condensed matter like solids and liquids only have one specific heat capacity, because their density changes are negligible. When heating a gas, it can expand and do pressure*volume work on its surroundings. Cv assumes that it is rigidly confined to keep a constant volume. Cp assumes it experiences constant pressure, and will do work equal to P*(V2 - V1) on its surroundings, as it heats from T1 to T2. We coin the concept of enthalpy (H) to equal the total destination of heat, when heating at constant pressure. H = deltaU + P*deltaV, where deltaU is the change in internal energy (that which is accounted-for in the molecular level KE values), and P*deltaV is the work it concurrently does on its surroundings. Since dH/dT and dU/dT aren't very temperature sensitive, and are approximately constant, we coin Cp and Cv as the temperature derivative of both of these terms respectively. Such that deltaH = Cp*deltaT, and deltaU = Cv*deltaT. In closed systems, keeping track of stored heat energy through internal energy is the most convenience. In open systems with flow, it is more convenient to use enthalpy.

It's really interesting how you can explain this in an 18 min. video while my prof. needs four 90 min. lectures and a convoluted mess of powerpoint presentations to literally tell me the same information...

And good luck.
Why do we use Cp instead of Cv in conduction equation?...for gases also Cp is used in standard heat transfer books.
Condensed matter like solids and liquids only have one specific heat capacity, because their density changes are negligible.
When heating a gas, it can expand and do pressure*volume work on its surroundings. Cv assumes that it is rigidly confined to keep a constant volume. Cp assumes it experiences constant pressure, and will do work equal to P*(V2 - V1) on its surroundings, as it heats from T1 to T2.

In closed systems, keeping track of stored heat energy through internal energy is the most convenience. In open systems with flow, it is more convenient to use enthalpy.
It feels extremely illegal to get all this knowledge for free.

Hope convection is on the way
