13.58 The end of a cylindrical liquid cryogenic propellant tank in free space is to be protected from external (solar) radi- ation by placing a thin metallic shield in front of the tank. Assume the view factor F, between the tank and the shield is unity; all surfaces are diffuse and gray, and the surroundings are at 0 K. T Shield, T, T, = 100 K E1 = E2 = 0.05 &= 0.10 Ĝ; = 1250 W/m? %3D Tank Solar irradiation Gs
