A plane wall of thickness L consists of three layers A, B, and C of equal thicknesses

and different thermal conductivities of kA, kB and kC respectively. Heat is generated in the middle

layer, B, at a constant rate of q per unit volume. Left side of the wall is at a temperature of T0 and

is insulated. Right side of the wall is subjected to convection heat transfer with coefficient of 'h'

and temperature of T .

(a) Plot temperature distribution for the wall.

(b) Is the temperature at the interface of layers A and B less than T0? Why?

(c) Is there a continuous slope for temperature distribution at the interface between layers B and C? Why?
