Estimate the rate at which heat can be conducted from the interior of the body to the surface (Hint: Search the internet for a formula that uses Thermal Conductivity). Assume that the thickness of tissue is 4.0 cm, that the skin is at 34°C and the interior at 37°C, and the surface area is 1.5 m2. The thermal conductivity of the tissue below the skin is 0.2 J/(s-m-°C). When you compare this to the measured value of about 230 W that must be dissipated by a person working lightly, it clearly shows that some of the heat must also be dissipated by the blood circulating through the body and not all the heat can be dissipated through the skin.
