Question:

Wind tunnels are used to measure the aerodynamic properties of prototype models.
(a) If a fan generates a wind speed of 25.0 mi/h inside an 8.75-ft2 section of a wind tunnel, what is the wind speed as the air enters the narrower, 4.35-ft2 section of the wind tunnel?
(b) Explain why it is often windier on city streets surrounded by tall buildings than in more open areas.
