10- A double pain insulated window unit is installed in a store. The unit consists of two 10mm thick pieces of glass (k=0.05 W/make) separated by a 18mm layer of air. The unit is 3m high and 4m wide. Determine the rate of heat transfer through the unit when the extreme outside surface of the glass is at -10C and the inside surface of the other pane of glass is at 20C. 10- A double pain insulated window unit is installed in a store.
