Problem 18AIP

When you exhale, all of the air in your lungs must exit through the trachea. If you exhale through your nose, this air subsequently leaves through your nostrils. The area of your nostrils is less than that of your trachea. How does the speed of the air in the trachea compared to that in the nostrils?

Step-by-Step Solution:

Solution 18AIP Introduction The equation of continuity for a fluid motion says that speed of a fluid passing through a given area is inversely proportional to the area. Step 1: Let, area of trachea = A 1 Speed of air through trachea = v 1 Area of nostril = A 2 Speed of air through nostril = v 2
