Consider the radiation heat transfer inside a cube with 0.5 meter sides. The top and bottom surface have an emissivity of = 0.25, with temperatures of Ttop" = 300 Kand Tbot = 600 K. The side surfaces are reradiating (no net heat transfer). The view factor between the top and bottom surface is F1_2 = 02 Find the net heat transfer into the bottom surface. a) 224 W b) 418 W c) 1536 W d) 2339 W Find the temperature of the side surfaces. a) 331 K b) 481 K c) 512 K d) 635 K Consider the radiation heat transfer inside a cube with 0.5 meter sides.
