Question:

Consider a plane wall of thickness L whose thermal conductivity varies in a specified temperature range as k(T)= k₀(1 + βT²) where k₀ and β are two specified constants. The wall surface at x = 0 is maintained at a constant temperature of T₁, while the surface at x = L is maintained at T₂. Assuming steady one-dimensional heat transfer, obtain a relation for the heat transfer rate through the wall.
