QUESTION 7 Consider a (1.25, 1.0, 1.3, 0.90)-m-high and (2.0, 2.1, 2.2, 2.3)-m-wide double-pane window (see Figure below) consisting of two 3-mm-thick layers of glass (k = 0.79 W/m.°c) separated by a 12-mm-wide stagnant air space (k = 0.028 W/m-°C). The room is maintained at (20, 21, 22, 23, 24) °C while the temperature of the outdoors is (5, 6, 7, 8)°C. Take the convection heat transfer coefficients on the inner and outer surfaces of the window to be h1 = 11 W/m2.0c and n2 = 22 W/m2.0c, and disregard any heat transfer by radiation. a. Draw the network of the thermal resistances. b. Evaluate each thermal resistance. c. Determine the steady rate of heat transfer through this double-pane window. 4. Determine the temperature of its inner surface for a day. Glass 12 3 mm Frame Save All AH
