The surface area of an adult human is about 1.8m2 . Suppose a person with a skin temperature of 34 ∘C is standing in a room where the air is 25∘C but the walls are 17 ∘C.
A) There is a "dead-air" layer next to your skin that acts as insulation. If the dead-air layer is 5.0mm thick, what is the person's rate of heat loss by conduction?
B) What is the person's net radiation loss to the walls? The emissivity of skin is 0.97.
