Consider a thin round plate at 350K with a radius of 18 cm is placed on a very large and very thick table of conductivity k = 1.6 W/mK. The plate has an emissivity of 0.6 and the temperature of the surrounding air and the table and the large room walls is 298 K. At this time, (a) How much heat (in W) is leaving via radiation? (b) How much heat (in W) is leaving via convection? (c) How much heat (in W) is leaving via conduction?
