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?

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
