Determine the wind speed if it exerts a pressure of 200 Pa. The wind blows perpendicular to the wall.

Determine the wind speed if it exerts a pressure of 200 Pa. The wind blows perpendicular to the wall. The air density should be taken equal to 1.29 kg / m3.

P = F / S
F * (delta) t = (delta) p – (p- pulse changes)
F * (delta) t = 2 * m * U, F = 2 * m * U / (delta) t
P = 2 * m * U / S * (delta) t, m = pV = p * S * l,
l / (delta) t = U, p = 1.29kg / m3
P = 2 * p * U ^ 2, U = √P / 2 * p = 8.8 m / s
