Assume that a woman must breathe a constant mass rate of air to maintain her metabolic processes. If sheinhales and exhales 16 times per minute at sea level, where the temperature is 59°F (15°C) and the pressureis 14.7 psia (101 kPa), what would you expect her rate of breathing at 18,000 ft (5486 m) to be? Usestandard atmospheric conditions.
