Heat flux trough non-homogeneous bar

  1. Aug 23, 2015 #1
    When you have the both sides of a non-homogeneous bar with thermal conductivities k1 and k2 in contact to 2 different temperatures, can you consider it the same as if there was some flux going through a homogeneous bar with the weighted mean of k1 and k2 as the conductivity?

    Yes, but you haven't told us whether they are in series or on parallel.
