A composite wall consists of a 13-mm-thick inner plaster board, a 192-mm-thick fiberglass blanket insulation, and a 20-mm-thick high-density particle board exterior panel. The thermal conductivity of the insulation is 0.035 W/mK. The inside and outside air temperatures are 20C and 0C, respectively. The convective heat-transfer coefficients in the inside and outside are 10 and 65 W/m^2K, respectively. (not sure if that is needed). K of plaster board is .17 W/mK. K of the particle board is .170 W/mK. Estimate the heat flux through the wall and plot the temperature distribution through the composite wall.
