Consider a 0.8 m high and 0.5 m wide window with thickness of 8 mm and thermal conductivity of k = 0.78 W/m °C. For dry day, the temperature of outdoor is -10 °C and the inner room temperature is 20°C. Take the heat transfer coefficient on the inner and outer surface of the window to be h₁ = 10 W/m² °C and h₂ = 40 W/m² °C which includes the effects of insulation. Determine: The steady rate of heat transfer through this glass window.
