Consider steady heat transfer between two large parallel plates at constant temperatures of T1 290 K and T2 150 K that are L 2 cm apart. Assuming the surfaces to be black (emissivity 1), determine the rate of heat transfer between the plates per unit surface area assuming the gap between the plates is: (a) filled with atmospheric air,
(b) evacuated,
(c) filled with fiberglass insulation, and
(d) filled with superinsulation h
