(a) Calculate the rate at which body heat is conducted through the clothing of a skier in a steady-state process, given the following data: the body surface area is 1.8 m2, and the clothing is 1.0 cm thick; the skin surface temperature is 33oC and the outer surface of the clothing is at 1.0oC; the thermal conductivity of the clothing is 0.040 Wm ∙ K.
(b) If, after a fall, the skier's clothes became soaked with water of thermal conductivity 0.60 Wm ∙ K, by how much is the rate of conduction multiplied?
