Nice presentation.
Which is the university?

[@currysteph1563]

What if using thermal resistivity?

[@luisc1402]

One thing that puzzles me about this method. The temperature of the A-B interface is not the same as the temperature of the A-C interface, is it? same for on the D side... How come that the circuit analysis works like this? What is the 'T' at the nodes that I am mentioning?

[@theadel8591]

The instructor should have mentioned the assumptions utilized in this particular example. One of them being that all surfaces normal to the x-direction are isothermal.

thank you

Tendencies of alternate molecules. Greg Holme's in delta A.

What will be the temperature profile for this case?

[@pranavkankal5604]

Can you tell me what will be temperature profile please 🙏🏻

[@samhithach3245]

In r (bc) the calculation is wrong pls check

[@peterburjorjee3352]

Thanks!

[@asheshshrestha]

@5:32 shouldn't the parallel resistance be R(b)'+R(c)' = [R(b)*R(c)]/[R(a)+R(b)]

[@trapmaster2222]

Please all note that temperatures in the problem are in ºC while in the solution are in ºK ...

[@AbhaySingh-wi4qu]

Doesn't matter we are concerned with temperature difference so the value will remain same

[@isai1331]

@@AbhaySingh-wi4qu True, the conversion only mater if you are going to divide or multiply temperature units

[@AbhaySingh-wi4qu]

@@isai1331 Exactly

[@AK-mc7gf]

this solution is wrong. Parallel resistance is calculated incorrect.

[@nylepentik2696]

Once again errors made in this video:
When summing up the total resistances, Rt = Ra + 1/ Rb + 1/Rc + Rd
This will give Rt= 32.79 K/W and hence, Q = 1.68W

[@franzandrewtiangco4809]

This is correct. The formula goes 1/Rbc = 1/Rb + 1/Rc, thus the -1 power in order to convert it back to Rbc.

[@soyboy1944]

B area is 0,4x0,5!! not 0,4, 0,4 is the length of one of its sides

[@remintwali2517]

The area is 0.4m2 (0.4m * 1m = 0.4m2)

[@ashviinalbano5121]

If you watch the video again, she explains that we should take the cross sectional area that the heat flux goes through.

@soy boy
you're such a soy boy for thinking that
