A plane wall is a composite of two materials, A and B. The wall of material A has uniform heat generation qG = 1.5 × 106 W/m3, kA = 75 W/m⋅K, and thickness LA = 50 mm. The wall material B has no generation with kB = 150 W/m⋅K and thickness LB = 20mm. The inner surface of material A is well insulated, while the outer surface of material B is cooled by a water stream with T∞ = 30°C and h = 1000 W/(m2⋅K). a. Sketch the temperature distribution that exists in the composite under steady-state conditions. b. Determine the temperature of the insulated surface and the temperature of the cooled surfac
