Sketch a simple diagram for electrical analog (Thermal Resistance), series and parallel for one-dimensional composite wall showing below, and write the heat transfer rate equation through the wall. 8 D 1 2 3 4 2. Corrected_text: Consider a 0.8 m-high and 1.5 m wide double-pane window consisting of two 4 mm-thick layers of glass k=0.78 W/mÂ°C separated by a 10 mm-wide stagnant air space k=0.026 W/mÂ°C. Determine the steady rate of heat transfer through this double-pane window and the temperature of its inner surface for a day during which the room is maintained at 20Â°C while the temperature of the outdoors is -10Â°C. Take the convection heat transfer coefficients on the inner and outer surfaces of the window to be h=10 W/mÂ²Â°C and h=40 W/mÂ²Â°C.
