The bernoulli effect can have important consequences for the design of buildings. for example, wind can blow around a skyscraper at remarkably high speed, creating low pressure. the higher atmospheric pressure in the still air inside the building can cause windows to pop out. this happened with the original design of the john hancock building in boston. (a) suppose a horizontal wind blows with a speed of 11.2 m/s outside a large pane of plate glass with dimensions 4.00 m x 1.50 m. assume the density of air to be constant at 1.20 kg/m3. the air inside the building is at atmospheric pressure. what is the total force exerted by air on the window pane? (b) what force is experienced by the window pane from air if the airspeed outside is now 22.4m/s the bernoulli effect can have important consequences for the design of buildings. for example, wind can blow around a skyscraper at remarkably high speed, creating low pressure. the higher atmospheric pressure in the still air inside the building can cause windows to pop out. this happened with the original design of the john hancock building in boston.
