Question

According to the graph above, when the wind velocity is 70 miles per hour, which of the following is closest to the pressure, in pounds per square foot?

• A. 13.5
• B. 14
• C. 15
• D. 16
• E. 16.5

Answer 1

The correct option is C 15

According to the graph,
when the wind velocity is $70$ miles per hour, the pressure is between $14$ and $16$.
hence, at wind velocity $70$, pressure is $15.0$
