Body heat is brought by the blood to the bottom layer of skin at a temperature of 37°C; the outer surface of the skin is at 30°C. A 165 lb (75 kg), 6 ft (1.83 m) person has a surface area of about 2 m2 and loses heat at a net rate of 75W while resting. Assuming an average skin thickness of 0.75 mm,
what is the thermal conductivity of this person's skin?
