Answer to Question #337505 in Physics for kaaru

Question

Calculate the rate of heat conduction out of the human body, assuming that the core internal temperature is 37.31 ºC, the skin temperature is 33.49 ºC, the thickness of the tissues between averages 1.46 cm, and the surface area is 1.27 m². (skin = 0.37W/m⋅°C)

Answer 1

$$P=\kappa\frac{\Delta T}{\Delta x}A$$

$$P=0.37*\frac{37.31-33.49}{0.0146}*1.27=123\:\rm W$$
