Consider a cylindrical evacuated enclosure of height 1m and radius 0.4 m. The top wall is
maintained at 400 K and has an emissivity of 0.8, while the bottom wall is at 800 K and is
black. The lateral wall of the enclosure is maintained at 600 K and has an emissivity of 0.4.
Evaluate the net radiative heat transfer from all the three surfaces and thereby verify the energy
balance.
