) Consider a 1.5-m-high and 3-m-wide glass window whose thickness is 6 mm and thermal conductivity is k = 0.88 W/m · °C. 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 27°C while the temperature of the outdoors is -7°C. Take the convection heat transfer coefficients on the inner and outer surfaces of the window to be h1= 11 W/m2 · °C and h2 =26 W/m2 · °C, and disregard any heat transfer by radiation
