5) A certain automobile has a 4 mm thick glass window with a surface area of 2.8 m². The outside temperature is 32°C while the passenger compartment is maintained at 22°C. The convection heat transfer coefficient on the exterior window surface is h = 90 W/(m²K). Determine the heat gain through the windows when the interior convection heat transfer coefficient is h = 15 W/(m²K). By controlling the air flow in the passenger compartment the interior heat transfer coefficient can...
