Solving Wind Force on Flat Roof Using Bernoulli's Equation

[mwahx3]

Homework Statement

If wind blows at 35 m/s over a house, what is the net force on the roof if its area is 240m^2 and is flat?

Homework Equations

Bernoulli's equation.

I think you can use dynamic pressure = $$\frac{density * velocity^2}{2}$$

Then use pressure = force/area.

To find the net force on the roof, compare the reduced pressure of the moving outside air to the pressure of the air within the house.
