Two parallel plates (A and B) separated by a vacuum are infinite in the directions perpendicular to their normals. From side opposite the face that faces plate B, plate A is supplied with a power input of 1 kW/m2. From plate B (which is maintained 400 °C below the temperature of Plate A), 1 kW/m2 is removed to the side not facing plate A, in order that a steady state can be maintained. If the emissivity of plate A is...

The interior surface of an oven of internal dimensions 1mx1mx1m has an emissivity of 0.8, and is maintained at a uniform temperature of 500 K. The oven is placed in a very large room where the ambient temperature is 300K. On the front wall of the oven is a square opening of dimensions 100mmx 100mm. To reduce the heat loss through the opening, a thin metallic plate is used to cover the opening. The emissivity of the cover plate surface...

Problem III - Solve on Booklet 3 (33 pts) Consider two parallel, aligned disks, 0.4 m in diameter and separated by 0.1 m. The first disk (A1), with an emissivity of 0.6, is maintained at a uniform temperature of 500 K. The second disk (A2), with an emissivity of 0.8, has a well-insulated back side while its front side faces the first disk. The two parallel disks are located in a large room (A3) whose walls are maintained at 300...
