Total thermal current?

Two metal cubes, with 2 cm sides, between 2 walls, one held at 100 C and the other at 0 C. The cubes are lead and silver.


a. Find the total thermal current through the cubes.


b. Find the temperature at the interface.

Total thermal current?
See the following reference:


http://en.wikipedia.org/wiki/Thermal_con...





ka (lead) = 35.4


kb(silver)=429





Note that this is a poorly defined problem


because there wll be two temperature at the interface.


One for the lead and one for the silver.


See the graph in that example:





There is also an equation there to plug the numbers into.





Actually...if you assume no contact resistance


then remove the 1/(hc*A) portion of the equation.


Since it wasn't mentioned...assume it is zero.
