Question

When air is inhaled, it quickly becomes saturated with watervapor as it passes through the moist upper airways. When breathingdry air, about 25 mg of water are exhaled with eachbreath. a)At 12 breaths per minute, what is the rate of energy lossdue to evaporation? Express your answer in watts. At bodytemperature, the heat of vaporization of water is Lv= 24e5J/kg the attempt to this problem: Q=MLv.....Q=(2.5e-5kg)(24e5 J/kg)= 60 J heat loss: Q/change in time.... 60 J/ (60 s ???).... how can irepresent 12 breath per minute...im i in the right path? b)At 12 breaths per minute, what is the rateof energy loss due to evaporation? Express your answer in Caloriesper day. When air is inhaled, it quickly becomes saturated with watervapor as it passes through the moist upper airways.
