Hurricane Force
During a hurricane, the atmospheric pressure inside a house may blow off the roof because of the reduced pressure outside.
If air (density 1.293 kg/m3) is blowing over the roof of a house at a speed of 108 km/hr, what is the pressure difference between the inside and the outside of the house?
5.82×102 Pa
What would be the lifting force on a roof of area 75 m2?
4.36×104 N

Does anyone have any ideas for starting this problem?

It's just the application of Bernoulli's principle.
