13.23 A long cylindrical rod of very high emissivity is heat treated within a long, evacuated oven of square cross section as shown in the sketch. The oven walls exhibit blackbody behavior. Due to nonuniform heat losses, the temperatures of the oven walls are slightly differ- ent and are T, = 600 K, T, = 575 K, T, = 555 K, and T, = 585 K, respectively. (a) Determine the steady-state temperature of the D = 0.2-m-diameter rod if each wall of the oven is w = 1 m wide and a = b = 0.5 m. (b) Determine the steady-state temperature of the rod when a = 0.5 m and b = 0.25 m. T3 D-
