A circular furnace has two end black surfaces and surface 1 is kept at 500 K and surface 2 is kept at 800 K. The diameter and the length of the furnace are 1.0 meters. Its lateral surface (surface 3) is also black and kept at 1000 K. Answer the following questions: 1. What is the view factor F12? 2. 3. 4. Draw the radiation network for this problem What is the heat transfer from the furnace (surf 3) to surface 1? What is the heat rate that need to be supplied to the lateral surface (surface3) to maintain this system?
