When you cough, you expel air at high speed through the trachea and upper bronchi so that the air will remove excess mucus lining the pathway.You produce the high speed by this procedure:You breathe in a large amount of air, trap it by closing the glottis (the narrow opening in the larynx), increase the air pressure by contracting the lungs, partially collapse the trachea and upper bronchi to narrow the pathway, and then expel the air through the pathway by suddenly reopening the glottis. Assume that during the expulsion the volume flow rate is 7.0 * 10-3 m3/s.What multiple of 343 m/s (the speed of sound vs) is the airspeed through the trachea if the trachea diameter (a) remains its normal value of 14 mm and (b) contracts to 5.2 mm?

Question

When you cough, you expel air at high speed through the
trachea and upper bronchi so that the air will remove excess mucus
lining the pathway.You produce the high speed by this procedure:You
breathe in a large amount of air, trap it by closing the glottis (the narrow
opening in the larynx), increase the air pressure by contracting
the lungs, partially collapse the trachea and upper bronchi to narrow
the pathway, and then expel the air through the pathway by suddenly
reopening the glottis. Assume that during the expulsion the volume
flow rate is 7.0 * 10-3 m3/s.What multiple of 343 m/s (the speed of
sound vs) is the airspeed through the trachea if the trachea diameter
(a) remains its normal value of 14 mm and (b) contracts to 5.2 mm?
