Reference no: EM131104410

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.

GIVEN

A double glazed window as shown

Inside room temperature (T?^?o) = 65°C

Outside air temperature (T?^?o) = 0°C

Cost of heating = $0.06/(kW hr)

ASSUMPTIONS

Saving can be based on steady state analysis

Inside and outside air is still

Radiative heat transfer is negligible
