A plane wall is a composite of three materials, A, B and C. The
wall of material A has uniform heat generation
q˙ of 100000 W/m3, kA
= 75 W/m K, and thickness LA = 60 mm. The wall material B
has no generation with kB = 150 W/m K and thickness
LB = 20 mm. The wall material C has no generation with
kC = 100 W/m K and thickness LC = 20 mm The inner
surface of material...
