Two perpendicular rectangular surface with a common edge have dimensions of 2m x 2m each. the rectangle surface 1 has an emissivity of epislion1 = 0.5 and temperature t1 = 227 celsius degree and the rectangle surface 2 has an emissivity of epislion2 = 0.8 and temperature of t2 = 27 celsius degree. the rectangle surface are surrounded by (large) ambient at unknown temperature t3. the heat transfer rate on surface 2 is zero. draw a schematic and label all relevant parameters a)find the surface resistance to radiation for surface 1, for surface 2, and for ambient. b)find the space resistance to radiation between surface 1 and ambient, surface 1 and surface 2, surface 2 and ambient. c)find the ambient temperature t3.
