1C) (5 pоints) In а mаnufаcturing prоcess, a cоating is attached between two substrates using radiative heating from above. Since the top substrate is glass, ALL radiation is absorbed at the top surface of the coating layer. Draw a thermal circuit including 1) all temperature nodes (T0 ~ T3), 2) arrows indicating the direction of heat flow (q, q1, q2) and 3) thermal resistances between temperature nodes. q1, q2 represent the heat flow within the substrates. Thicknesses of the layers are shown in the schematic below. Thermal conductivities of the materials are ks1 for the top substrate, ks2 for the bottom substrate, and kc for the coating. Write the thermal resistance expressions using the symbols for thicknesses, thermal conductivities and convection coefficient. Do NOT need to perform any calculation and ignore contact resistances.
