Consider a 1.2-m-high and 2-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.
