Heat Transfer
(20) Radiation is emitted from a small opening (A 10 m2) of a furnace in which surface temperature is constant to be 2000K. The inner surface of the furnace is diffuse and gray (E-0.5). A portion of this radiation is intercepted by three detectors that are 0.5m from the aperture as shown below. The area of three detectors is the same as 10 m2 The area of the opening of the furnace and detectors can be considered as...

Problem 2: A small surface A1, with area 7 cm2, emits radiation as a blackbody at 800K. Part of its radiation hits another small surface A2, with area 7 cm2, which is oriented as shown in the figure below. (a) Determine the solid angle of A2 as viewed from Aı. (b) Determine the radiation heat transfer rate (in W) from A1 to A2. Hint: you can assume the surfaces are small relative to their separation distance Problem2 02-60A2 r-80 cm...

6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
