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 area
