A hurricane wind blows across a 6.0mX15.0m flat roof at a speed of 130 km/h. Is the air pressure above the roof higher or lower than the air pressure inside the house? What is the pressure difference? How much force is exerted on the roof? If the roof cannot withstand the force, will it blow in or out?
