- Homework Statement
- The room has double glazing windows. Each window has a dimension of 100cmx30cm and is constructed by sandwiching a 3mm air gap between the two glass panels. Calculate the power required to maintain the temperature of the room at 27 degrees.
- Relevant Equations
- q = Q/A = -kdT/dx
In this case with a presence of the airgap, what should I do with the equation that is provided to be? Must the temperature gradient be caculated spearately (glass+air+glass) ? My tutor provided the hint that the heat flux should be constant for the windows, so in this case should I just omit the air? If so, why?
Thanks.
