Consider a 320 mm x 320 mm window in an aircraft. For a temperature difference of 80°C from the inner to the outer surface of the window, calculate the heat loss through L = 10-mm-thick polycarbonate, soda lime glass, and aerogel windows, respectively. The thermal conductivities of the aerogel and polycarbonate are kag = 0.014 W/m-K and k pc = 0.21 W/m-K, respectively. Evaluate the thermal conductivity of the soda lime glass at 300 K. If the aircraft has 110 windows and the cost to heat the cabin air is $1/kW-h, compare the costs associated with the heat loss through the windows for an 8-hour intercontinental flight.
