Question

Figure 23-2 Mechanics of Ventilation
 
Use Figure 23-2 to answer the following questions:
-What is the relationship between the pressures at label "3"?
A) P outside = P inside 
B) P outside > P inside 
C) P outside < P inside 
D) P outside + P inside 
E) P outside - P inside

Quizplus · Accepted Answer

The pressure outside (P outside) is greater than the pressure inside (P inside) due to the Bernoulli's principle, which states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure.
