- The Bernoiulli effect can have important consequences for the design of buildings. For example, Wind can blow aorund a skyscraper at remarkably high speed, creating low pressure. The higher atmospheric pressure in the still air inside the buildings can cause windowspanes that fell many stories to the sidewalk below a) Suppose a horizontal wind blows with a speed of 11.2 M/s outside a large pabe of plate glass with dimensions 4.00m x 1.50m Assume the density of the air to be constant at 1.20kg/m3 The air inside the building is at atmospheric pressure. What is the total force exerted by air on the windowpane? b) What if a sencond skyscraper is built nearby, the airspeed can be especially high where wind passes through the narrow separation between the buildings. Solve part (a) again with a wind speed of 22.4m/s, twice as highThis Cannot be hand-drawn, this physics solution must be typed out, and the explanation in the simplest manner.E1.
