How to Calculate Wind Pressure on a Wall?

[jackamo321]

The wind in a severe storm is blowing 30 ms perpendicularly to the wall of a large barn of area 80 m2. Calculate the pressure exerted on it, assuming that the air density is 1.3 kg m3.

I am quite new to this unit so i really have no idea what to do. Any help apreciated!

From Bernoulli's principle:
Wind Pressure = ½ x (density of air) x (wind speed)²

wow, thanks a lot!

Check the question it asks for the wind pressure but gives a wall area, does it ask for total force or pressure?

That is the exact question that i have written, but i presume it means the force that the wind is pushing at the wall with.
