A circular disk of diameter Di 20 mm is located at the base of an enclosure that has a cylindrical sidewall and a hemispherical dome. The enclosure is of diameter D-0.5 m, and the height of the cylindrical section is L 0.3 m. The disk and the enclosure are black and at temperatures 1000 K and 300 K, respectively.
(a) What is the net rate of radiation exchange between the disk and the hemispherical dome?
(b) What is the net rate of radiation exchange between the disk and top third of the cylindrical section (e. g. the section of the cylindrical sidewalls between the hypothetical surfaces Azand A3)?
