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

A hollow cylinder of length L has inner radius, r1, outer radius, r2 , and

thermal conductivity, k. It is in dynamic thermal equilibrium, with its interior

held at temperature T1 and its exterior at a different temperature, T2. What is the

radial temperature dependence, T(r), within the cylinder, r1 ≤ r ≤ r2 ?

2. Relevant equations

Heat Current = KA(T-T)/L

3. The attempt at a solution

I know heat current out equals heat current in and than you solve for T. However, I cannot figure out how to calculate the heat currents since the area is changing.
