EML 4147C 3 problems 1. The radiation laboratory is involved with the thermal radiation measurement. The apparatus is composed of a blackbody simulator and a Moll's thermopile that is used to measure the net rate of radiant energy absorbed. A water-cooled, disk shaped radiation shield covers the face of the blackbody cavity that is maintained at 600 ˚C by an oven and the blackbody cavity has a 2 cm diameter aperture through which thermal radiation passes. The aperture opening of the thermopile is 2.5 cm in diameter. The thermopile can be approximated as a blackbody also. It is

Unformatted text preview: important to note that the two apertures are all vertical and facing each other with their centers on a straight line as shown in the figure below. The separation distance between the two apertures is W. Please predict the net rate of thermal radiation from the thermopile at 105 C for L equal to 15 cm and 40 cm, respectively. 2.5 cm 2 cm L Blackbody Aperture Receptor Aperture 2.
