Consider a cold winter day with an air temperature of 5 degrees C and relative humidity of 20% (moisture content .001g H2O/ g dry air). A person waiting at a bus stop inhales at an average rate of 7g dry air /minute and exhales air saturated with water at body temperature (37 degrees C) and 1 atm. The heat capacity of dry air is 1.05 J/(g*degreeC). Estimate the rate of heat loss by breathing in kcal/hr.
