Question:
Air moves through the human trachea at ms during inhalation. A constriction in the trachea leads to a doubling in the air speed. Find the approximate pressure change at the constriction versus that in an unconstructed trachea Use a density for air of kgm
Enter a negative pressure difference for a pressure drop and a positive pressure difference for a pressure gain
Delta
P
Pa
Is this pressure change significant?
A The pressure change is significant.
B The pressure change is negligible very small
C The pressure change is moderate.
