A clever student decides to produce and sell windows that consist of two 5.9-mm thick glass panes ( thermal conductivity of 1 W/m-K) separated by a 0.9-cm thick layer of aerogel, which has a thermal conductivity of 10-4 W/m-K). Assuming the temperature inside is 19.5˚ C, and the temperature outside is -4.7˚C, what is the approximate heat loss in units of Watts through such a window with area 1 m2?
