A double-pane glass window shown in Figure P13–9, consists of two 4-mm thick layers of glass with k = 0.80 W/m-° C separated by a 10 mm thick stagnant air space with k = 0.025 W/m-° C. Determine (a) the temperature at both surfaces of the inside

layer of glass and the temperature at the outside surfaces of glass, and (b) the steady rate of heat transfer in Watts through the double pane. Assume the inside room temperature T_i∞ = 20 ° C with hi = 10 W/m²-° C and the outside temperature T_0∞ = 0 °C with h₀ = 30 W/m²-° C. Assume one-dimensional heat flow through the glass.
