The document describes a problem involving calculating the heat loss through a double pane window. It is given that the window dimensions are 0.914m x 1.83m and that each of the glass layers is 6.35mm thick, separated by a 6.35mm layer of stagnant air. The thermal conductivities of the glass and air are provided. The problem is to calculate the heat loss for the given temperature drop of 27.8K across the system.
