A cylindrical rod of length 50 cm and cross-sectional area 1 cm is fitted between chamber at oC and an evacuated chamber maintained at 27°C as shown in figure Only portions of the rod are inside the chambers and the rest is thermally insulated from surrounding. The cross section going into the evacuated chamber is blackened so that completely absorbs any radiation falling on it. The temperature of the blackened end is when steady state is reached. Stefan constant o = 6 x 10- W m-2 K-. Find the thermal Inductivity of the material of the rod. 17°C 0°C 27°C

A cylindrical rod of length 50cm and cross sectional area 1cm^(2) is fitted between a large ice chamber at 0^(@)C and an evacuated chamber maintained at 27^(@)C as shown in figure. Only small protions of the rod are insid ethe chamber and the rest is thermally insulated from the surrounding. The cross section going inti the evacuted chamber is blackened so that it completely absorbe any radiation falling on it. The temperatuere of the blackened end is 17^(@)C when steady state is reachhed. Stefan constant sigma=6xx10^(-s)Wm^(-2)K^(-4) . Find the thermal conductivity of the material of the rod.

A cylindrical rod of length l and cross - sectional radius r is placed at a distance of 50 r from a infrared point source S of power 1.25 kw as shown in the figure. The lateral surface of the rod is perfectly insulated from the surroundings . If the cross - section A absorbs 80 % of the incident energy and the temperature difference between the ends of the rod is constant , then the rate of heat flow through the rod in steady state is
