Q/A$) is constant through the wall and its surfaces.

You're on a roll — here are the solutions to the heat transfer problems.

3) Plane wall with variable thermal conductivity

Step 1: Define the heat transfer rates. The heat transfer rate per unit area ( $q = Q/A$ ) is constant through the wall and its surfaces. For convection at surface 1: $q = h_1(T_{\infty 1} - T_1) = 250(130 - T_1) \quad (1)$ For convection at surface 2: $q = h_2(T_2 - T_{\infty 2}) = 500(T_2 - 30) \quad (2)$ For conduction through the
