Calculate the rate at which body heat flows out through the clothing of a skier, given the following data. The body surface area is 1.8 m2 and the clothing is 1.0 cm thick; skin surface temperature is 33o C, whereas the outer surface of the clothing is at -5oC; the thermal conductivity of the clothing is 0.04 W/mK.
How would the answer change if, after a fall, the skier's clothes become soaked with water? Is the answer much different or not? What does this teach you about falling into a pond while skiing?
