Consider a glass window that is 5mm thick, 60cm wide, and 90cm tall and has a thermal conductivity of 0.96 w/m*k. how much heat is lost through this glass window versus a 10-cm thick brick wall (k = 0.69 w/m*k) with the same width and height if the inside surface temperature is 23°c and the outside surface temperature is 0°c? we know temperature of the surface so we can ignore any heat loss due to convection. a large fan blows hot air at 85°c over a 3m x 9m flat surface with a surface temperature of 37°c. previous experiments indicated that the heat transfer coefficient is 50 w/m2*k. determine the rate of heat transfer from the air to the plate.
