Determine the rate of heat loss through a double glazed window, as shown in the sketch, if the inside room temperature is 65?C and the average outside air is 0?C during December. Neglect the effect of the window frame.

If the house is electrically heated at a cost of $0.06/(kW hr), estimate the savings achieved with a double glazed compared to a single glazed window during December.GIVENA double glazed window as shownInside room temperature (T??o) = 65?COutside air temperature (T??o) = 0?CCost of heating = $0.06/(kW hr)ASSUMPTIONSSaving can be based on steady state analysisInside and outside air is stillRadiative heat transfer is negligible
