A square thermal window is constructed of two sheets of flat glass, each 4.00 mm thick, separated by 5.00 mm of still air. If the inside of the window is at 20.0°C, the outside at - 30.0°C, and the cross-sectional area of the window is 6.00 m², determine for the steady state: W m. K k is Thermal conductivity kglass = 0,80- W m. K Kair= 0,024- a) The temperatures between the air layer T1 and 72 indicated in the figure. b) The flow of heat through the window. c) If the air layer is removed and the two glass sheets are glued together. What is the new heat current? Is the standing air layer important? And discuss what would happen if the air between the two glasses were not stationary.
