CAlculate wind load using fluid impulse and momentum.

I recently took a crash course that included some topics in fluid mechanics. I learned that you can use the concept of impulse and momentum the calculate the force of fluid, for instance a jet of water on a turbine blade. The equations used are:

ƩFx = ρQ(Vx1-Vx2)
ƩFy = ρQ(Vy1-Vy2)

I realize that as a gas air is compressible, but I was wondering if I could calculate wind loading on a wall using the same concept, but maybe with a factor of compressibility factored in. If I treat air as an incompressible fluid, will I get a wind load that is reasonably close to the actual wind load?

Thanks
