A hurricane wind blows across a 6.00 m times 15.0 m flat roof at a speed of 190 km/hr.
Is the air pressure above the roof higher or lower than the pressure inside the house? Explain.
p + (1/2) rho v^2 = constant
where v is high, p is low.
v --> 0 at house wall so pressure is high at open window (something will be open because force breaks window)
so the pressure is higher inside and roof is lifted up.
