PROBLEMS
5.1 Consider a double-pane window with two glass layers separated by
air. Explain what happens to total thermal resistance of this double-
pane window if temperature increases. Assume thermal conductivity
of glass does not change with temperature and there is no convection
and radiation heat transfer through the air.
5.2 Write down expressions for conduction thermal resistance, convection
thermal resistance, and radiation thermal resistance.
5.3 What is thermal contact resistance?
5.4 How does thermal contact resistance between two surfaces change
with temperature? Why?
5.5 How does
