Consider a 1.5-m-high and 2.4-m-wide glass window. whose thickness is 6 mm and thermal conductivity is k = 0.78 w/m·k. determine the steady rate of heat transfer through this glass window and the temperature of its inner surface for a day during which the room is maintained at 24°c while the temperature of the outdoors is −5°c. take the convection heat transfer coefficients on the inner and outer surfaces of the window to be h1, = 10 w/m2·k and h2 = 25 w/m2·k, and disregard any heat transfer by radiation.
