ok, I got the change in pressure to be 1625 Pa, which is correct. I plug that into F = pA and get F = 1625Pa * 93.6m^2 = 152100, this seems too big. I got it right, thank you!

1.A hurricane wind blows across a 7.8 m x 12 m flat roof at a speed of 180 km/hr. What is the pressure difference? How much force is exerted on the roof? 2. Homework Equations P= p_atmos + pgd P=F/AThe Attempt at a Solution p = 101300Pa - (1.3)(9.8m/s^2)(93.6m^2) p = 100107.5Pa 100107.5Pa =...
