You are designing a panel on a satellite. Its purpose is to radiate heat away from the satellite. The panel will be square, 0.50 m along each edge, and it needs to radiate 200 W of power. (Because it's facing the blackness of outer space, there is negligible radiation being absorbed from space by the panel.) (1) Assuming its emissivity is 0.23, what will be its (outer) surface temperature? (2) The heat being radiated has to flow through the panel from its inner to its outer surface. What must be its inner surface temperature to maintain a steady 200 W of outward heat flow through the panel? Assume the panel is a 1-cm thick piece of stainless steel, for which the conductivity is 20 W/m•K.
