Consider steady heat transfer in an L$-$shaped solid body whose cross section is given in the Figure below. Heat transfer in the direction normal to the plane of the paper is negligible, and thus heat transfer in the body is two$-$dimensional. The thermal conductivity of the body is $k=15W{m}^{-1}{C}^{-1},$ and heat is generated in the body at a rate of $2{10}^{6}W{m}^{-3}.$ The bottom surface is maintained at a uniform temperature of $170C.$ The entire top surface is subjected to convection to ambient air at $T=10C$ with a convection coefficient of $h=80W{m}^{-2}C,$ and the right surface is subjected to heat flux at a uniform rate of $q=5000W{m}^{-2}.$ The boundary on the left side is not known. The nodal network of the problem consists of $11$ equally spaced nodes with $x=y=1\mathrm{.}2$ cm as shown in the figure. Evaluate the temperature T$6$ in $C$ rounded to one decimal place, if the temperature T$7$ is $151C$
