Consider heat transfer through an insulated frame wall of a house. The thermal conductivity of the wall is \(0.055 \mathrm{~W} /\left(\mathrm{m} \cdot{ }^{\circ} \mathrm{C}\right)\). The wall is \(0.15 \mathrm{~m}\) thick and has an area of \(15 \mathrm{~m}^{2}\). The inside air temperature is \(20^{\circ} \mathrm{C}\) and the heat transfer coefficient for convection between the wall and the inside air is \(2.6 \mathrm{~W} /\left(\mathrm{m} \cdot{ }^{\circ} \mathrm{C}\right)\). On the outside of the wall, the heat transfer coefficient for convection between the wall and the outside air is \(10.4 \mathrm{~W} /\left(\mathrm{m} \cdot{ }^{\circ} \mathrm{C}\right)\) and the outside air temperature is \(-10^{\circ} \mathrm{C}\). Determine the heat flow rate through the wall.
