Three identical rods are joined in series as shown. Their thermal conductivities are `K, K//2` and `K//3` respectively. At steady, if the free ends of rods are at `100^(@)C` and `20^(@)C` respectively. Determine the temperature at two junction points. Also find the equivalent thermal conductivity.

Three cylindrical rods A, B and C of equal lengths and equal diameters are joined in series as shown if Fig. Their thermal conductivities are 2K, K and 0.5K, respectively. In steady state, if the free ends of rods A and C are at 100^@C and 0^@C , respectively, calculate the temperature at the two junction points. Assume negligible loss by radiaiotn through the curved surface. What will be the equivalent thermal conductivity?
