A student in a lecture hall has 0.25 m 2 of skin (arms, hands, and head) exposed.

Question:

A student in a lecture hall has 0.25 m²of skin (arms, hands, and head) exposed. The skin is at 34°C and has an emissivity of 0.97. The temperature of the room is 20°C (air, walls, ceiling, and floor all at the same temperature).

(a) At what rate does the skin emit thermal radiation?

(b) At what rate does the skin absorb thermal radiation?

(c) What is the net rate of heat flow from the body due to thermal radiation? Compare this to the total rate of heat flow from the body, about 100 W.
