The lung has a total capacity of 6000 mL. Air with a density of 1.225 kg/m3 is expired through the trachea (d-1.8 cm) at a velocity of 20 cm/s. Calculate the time rate of change in air density during expiration. Assume that lung volume is decreasing at a rate if 100 mL/s. Answer: 0.01 kg/(m3.s) Trachea Broncus Bronchiole -Alveoli The lung has a total capacity of 6000 mL.
