i Need help with this heat transfer homework problem. I would greatly appreciate the help.
A thermopane window consists of two pieces of glass with a thickness of L glass each. The two glasses enclose an air space with a thickness of L gap. The window separates room at T room from outside ambient air at T out (T room >T out ). The convection heat transfer coefficient associated with the inner (room side) surface is h i and the convection coefficient associated with the outer ( ambient) air h o . The window has a length of H and a width of W. The radiation is neglected . The air enclosed between the panes is assumed to be stagnant. The thermal conductivity of the glass is K glass and the air thermal conductivity is K air 1. Sketch the equivalent thermal circuit of the system , and express all the resistances in terms relevant variables . Label heat flow direction 2. What is the heat loss through a window. 3. If the heat transfer by radiation is taken into consideration on the outer surface, and the surrounding temperature T sur =T out . Re-sketch the normal circuit
