hey would anyone care to explain this to me?
Two panes of glass each have a thickness of 0.45 cm. What is the ratio (in percent) of the rate of heat flow through a double pane window constructed by leaving a 0.225 cm air gap between the panes to the rate of heat flow through a single 0.45 cm pane for the same temperature difference? kair = 0.027 W/mK and kglass = 1.0 W/mK
to be honest. im not exactly sure how to start the problem. the equation for rate flow is R=KA((T1-T2)/L)
