The space between the panes of a double-glazed window can be filled with either air or carbon dioxide at atmos- pheric pressure. The window is 1.5 m high and the spac- ing between the panes can be varied. Develop an analysis to  predict  the  convection  heat  transfer rate  across  the window  as  a  function  of  pane  spacing  and  determine, under otherwise identical conditions, whether air or car- bon dioxide  will  yield  the  smaller  rate.  Illustrate  the results of your analysis for two surface-temperature conditions: winter (-10°C, 20°C) and summer (35°C, 25°C).
