A $17-$m$-$high and $5-$m$-$wide wall consists of long $16-$cm x $22-$cm cross section horizontal bricks $($k $=0\mathrm{.}72$ W$/$m $\backslash$deg C$)$ separated by $17-$cm$-$thick plaster layers $($k $=0\mathrm{.}22$ W$/$m $\backslash$deg C$).$ There are also $2-$cm$-$thick plaster layers on each side of the brick and a $17-$cm$-$thick rigid foam $($k $=0\mathrm{.}026$ W$/$m $\backslash$deg C$)$ on the inner side of the wall, as shown in Fig. $17-21.$ The indoor and the outdoor temperatures are $20\backslash$deg C and $-10\backslash$deg C$,$ respectively, and the convection heat transfer coefficients on the inner and the outer sides are h$,=10$ W$/$m$?.\backslash$deg C and h$2=25$W$/$m$?.\backslash$deg C$,$ respectively. Assuming one$-$dimensional heat transfer and disregarding radia$-$tion, determine the rate of heat transfer through the wall.
