Exhaled air is ordinarily at body temperature and 100% humidity (i.e., it is fully saturated with water). Estimate the mass of H2O that is lost each day because of normal breathing. The saturation vapor pressure (SVP) of water at 37◦C is 47 mmHg and contains 44 mg/L of water, whereas at room temperature (20◦C) it is 20 mmHg and contains only 18 mg/L.
