A composite rod made of thre and cross section as shown in the fig The thermal conductivities of the materials of the rods are K 2 5K and K respectively The end A and end B are at constant temperatures All heat entering the face A goes out of the end B and there being no loss of heat from the sides of the bar The effective thermal conductivity of the bar is 42 A K 2 1 15K 16 3 5K 16 1 5 C 5K k The figure shows the face and interface temperature of a composite slab containing of four layers of two materials having identical thickness Under steady state condition find the value of temperature 0 20 C 10 C 0 5 C 10 C 2k k 2 6K 13 4 2K 13 2k K k thermal conductivity 2 10 C B
