Onsider a poor lost soul walking at 5 km/h on a hot day in the desert, wearing only a bathing suit. this person's skin temperature tends to rise due to four mechanisms: (i) energy is generated by metabolic reactions in the body at a rate of 300 w , and almost all of this energy is converted to heat that flows to the skin; (ii) heat is delivered to the skin by convection from the outside air at a rate equal to k′askin(tair−tskin), where k′ is 54 j/h⋅∘c⋅m2, the exposed skin area askin is 1.5 m2, the air temperature tair is 48 ∘c , and the skin temperature tskin is 36 ∘c; (iii) the skin absorbs radiant energy from the sun at a rate of 1400w/m2; (iv) the skin absorbs radiant energy from the environment, which has temperature 48 ∘c
