Two Parallel Rectangles Have Emissivities Of 0 6 And 0 9 Respectively These Rectangles Are 1 2 M Wide And 2 4 M High A 1 (13.31 KiB) Viewed 32 times
Two parallel rectangles have emissivities of 0.6 and 0.9, respectively. These rectangles are 1.2 m wide and 2.4 m high and are 0.6 m apart. The plate having & = 0.6 is maintained at 1000 K and the other is at 420 K. The surroundings may be considered to absorb all energy that escapes the two-plate system. Determine: a. the total energy lost from the hot plate, b. the radiant energy interchange between the two plates.
