Lecture 06: 1D Steady State Heat Conduction In Plane Wall With Generation of Thermal Energy

[@jay.jay.]

I just wanted to say THANK YOU so much because your explanations are so clear. Unfortunately my professor didn't explain much concepts, so had to search myself to understand them better and these lectures come so in handy to me. Thank you again!

• Heat Transfer rate in two conditional formulations - (I) Steady state : 1. Net accumulation of heat at any instant in time is zero. That means heat transfer is such that as soon as heat in fluxes comes they immediately goes out (Almost in no time or simultaneously) at any unit volume or mass throughout the body. 2. Hence, at any point in the body, its temperature remains unchanged with time though it can be variable or constant with position or space in the body. 3. Temperature is only function of space coordinates or constant but independent of time. 4. Used with approximation & accuracy for heat transfer in large or infinitely large time scale. (II) Unsteady state : 1. There is net accumulation of heat at any instant in time & hence, it stores some heat which gives temperature to change with time. 2. In this situation, net incoming & outgoing heat fluxes are not same. There is some finite delay in balancing these fluxes at any point or volume in time. 3. Here, temperature is function of time also along with space coordinates. 4. Used usually for heat transfer in finite time scales or sometime in large time scales also where temperature change with time is necessary to investigate in depth.

The man with 0 haters❤️ Sir❤️

Sir alway miss you❤❤❤ RIP.

38:32 When he is defining the cross sectional avg temperature, will the numerator be TLdy or just Tdy? Because for what he has written, doesn't match the dimensions with temperature

[@adarshsingari2040]

L term wrongly written by sir

[@swabhiman12345]

This man is excellent 👌👌👌

Dhanyawad Sir Ji

[@UCHMAULIKSOLANKISVNIT]

superb video sir..

[@aniketsen6845]

Great lecture❣

[@chetansuralkar6701]

can anyone plz explain 17:32 ? how he got final value -4/L?

[@rubixcubesolve]

hey took derivative of-4x^2/L^2 which is -8x/L^2 and plugged in L/2 which gives-4/L

[@chetansuralkar6701]

thank you

[@VibhorVerma28]

nice..very conceptual

[@Aks0417]

For boundry conditions instead of L/2 L would yield easier results

[@muhammadipank9204]

can i download this video , for study

You will be sued

[@junaidbaig7080]

can someone explain me t 13:57 why did he wrote T instead of Tw

[@prathameshdand4418]

Use of 1+ and lhs.... Rhs is shifted to lhs

[@naveensingh9237]

Conduction and convection was too tough for me .

[@meetp9492]

for me too!!!
