1) Determine the view factors F13 and F23 between the rectangular surfaces shown in Figure below: F32=0.05 2 m A2 1 m 1 m A3 1 m 2) Determine the view factor F12 between the rectangular surfaces shown in Figure below. 1 m I m 2 m I m 1 m 2 m 1 m 1 m Í m 3 m 2 m 3 m (b) (c) (a) B) F14=0.07 C) F12= 0.08 A) F12 0.07 3) Two parallel disks of diameter D=0.6 m separated by L =0.4 m are located directly on top of each other. Both disks are black and are maintained at a temperature of 700 K. The back sides of the disks are insulated, and the environment that the disks are in can be considered to be a blackbody at T-300 K. Determine the net rate of radiation heat transfer from the disks to the environment. Answer: 5505 W
