Two parallel, aligned disks, with diameter D$=0\mathrm{.}35$m and separated by L$=0\mathrm{.}1$m$,$ are located in a large room$($surface $3)$ whose walls are maintained at T$\_(3)=300$K$.$ One of the disks $($surface $1)$ is maintained at a uniform temperature of T$\_(1)=600$K with an emissivity of $0\mathrm{.}8,$ while the back side of the other disk $($surface $2)$ is insulated. The disks are diffuse, gray, and opaque surfaces. Determine the temperature of the insulated disk, T$\_(2).$ In solving this problem, you will need to draw one thermal circuit. PLEASE SOLVE THE PROBLEM BY HAND PROVIDE FULL THERMAL CIRCUIT. PROVIDE DETAILED WORK TO GET T$\_(2.)$
