Wind blows around a skyscraper with a speed of 18 m/s outside a large pane of plate glass. What is the difference in air pressure between the inside and outside of the skyscraper? Take the density of air to be 1.3 kg/m3 and assume the air inside the skyscraper is still.
According to the Bernoulli equation,
delta P = (1/2)*(air density)*V^2
V is the outside velocity, 18 m/s
The pressure difference will be in Pascals
