(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Rod of cross sectional area A and length l has its left end held at constant temperature t1 and its right end held at t2<t1. If the conductivity varies with distance from the left end, x, according to the relationship k= x/R + k0 (R and k0 are positive), what is the steady state heat flow, H, through the rod.

2. Relevant equations

heat flow = kA*((t1-t2)/l)

3. The attempt at a solution

I've always had a hard time understanding what to integrate and what to take the derivative of. As far as I know, I need to integrate k from some x to some final x...
