Two plane disks each 125 cm in diameter are parallel and directly opposite each other. They are separated by a distance of 50 cm. Disk A is heated by electrical resistance to 833.3 K. Both disks (A and B) are insulated on all faces except the two faces directly opposite each other. Assume that the surroundings emit no radiation disks are in space. the a) Determine view factor F₁: from disk A to disk B. b) Calculate the temperature of disk B at steady state.
