The equation of continuity:
From the equation of continuity, the speed of the hurricane wind increases at the outside of the roof.
Inside the roof, the pressure is greater and the velocity is smaller.
A hurricane wind blows across a 7.50 m x 11.2 m flat roof at a speed of 190 km/hr.
a) Is the air pressure above the roof higher or lower than the pressure inside the house? Explain.
b) What is the pressure difference?
