Consider one-dimensional conduction in a plane composite wall. The outer surfaces are exposed to a fluid at 25°C and a convection heat transfer coefficient of 1000 W/m2 ⋅⋅ K. The middle wall B experiences uniform heat generation q B, while there is no generation in walls A and C. The temperatures at the interfaces are T1 = 261°C and T2 = 211°C.
