Homework Help: Fluids (bernoulli's equation)

  1. Sep 26, 2005 #1
    During high winds, the atmospheric pressure inside a house may blow off the roof because of the reduced pressure outside. Calculate the force on a square roof of side 22.0 m if the wind speed over the roof is 29.0

    i used bernoulli's equation and got an answer of... 246356N
    i used 1.21 as the density of air. could someone check my work please?

    Pi = Po + 0.5d V^2
    F = (Pi-Po)A = 0.5 d V^2 ; d is the density = 1.293 kg/m^3
