Question:
The surface area of an adult human is about 1.8 m^2. Suppose aperson with a skin temperature of 34C is standing nude in a roomwhere the air is 25C but the walls are 17C. There is a \"dead-air\"layer next to your skin that acts as insulation. If the dead-airlayer is 5.0mm thick, what is the person\'s rate of heat loss byconduction? What is the person\'s net radiation loss to the walls?The emissivity of skin is 0.97. Does conduction or radiationcontribute more to the total rate of energy loss? If the person ismetabolizing food at a rate of 160W, does the person feelcomfortable, chilly, or too warm?
