Two rooms are separated by a wall that is wood panel, r= 0.93 (usual units) on one side, with fiberglass insulation r = 13.0 between the walls and wall board r = 0.46 on the other. one room is air conditioned at 74 deg. f and the room is not air conditioned at 92 deg. f. film coefficients are r = 0.68 on both walls. what is the heat transfer rate from the warm room to the cool room? neglect the heat transfer reduction by the wall studs.
