"Wind (density=1.29kgm^-3) blows over a flat roofed building of height 20m at 12ms^-1.The area of he roof is 100m^2.What is the magnitude and direction of the force exerted on the roof if the pressure difference between inside and outside is due solely to the fact that the inside air is still?Assume laminar flow."

2. Relevant equations

Im really stumped with this Q, I have scanned the net and it seems to involve the Bernoulli Eqn , however, i dont really understand whats occuring, any help appreciated.

3. The attempt at a solution
