Wind exerting pressure on wall

  1. Nov 6, 2008 #1
    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

    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.
