1. The problem statement, all variables and given/known data 2. Relevant equations d/dx(kdT/dx) + S = 0 (for steady state) q_cond = -kAdT/dx q_gen = S*Vol 3. The attempt at a solution So I tried to equate q_cond to q_gen but it seemed to give me the wrong answer. Does anyone know why? I believe to get the right answer I have to use the first equation I wrote in the relevant equations section. Does my method not work because S is not uniform? But then it tells me that at x = 0, S = So so it shouldn't matter since we have a boundary condition?
