okay we've got a heat transfer example problem here in this problem we're going to use fourier's law when given a temperature profile or a temperature distribution to also calculate a flux distribution or a flux profile so this problem states that if we have a solid rectangular block with the temperature profile given by this equation the temperature as a function of x y and z is equal to 40 x squared times y plus 3 times natural log of y plus 2.5 times x times z if we know the thermal conductivity we want to develop expressions for the flux in each of those directions x y and z and then we also want to put all those different flux components together to comprise the entire vector which would have both magnitude and direction so basically what we're asking is let's say we have a big solid block of stuff solid material that might look something like this so we would be looking at a tempe
