1) density of air 1.2 kg/m3
A hurricane with wind speed 35 m/s is acting on a 10 m2 wall. The dynamic force can be calculated as
Fw = 1/2 ρ v2 A
= 1/2 (1.2 kg/m3) (35 m/s)2 (10 m2)
= 7350 N
= 7.35 kN
Or - from the table above the wind load per square metre is 735 N/m2. The total load on the wall can be calculated as
(735 N/m2) (10 m2) = 7350 N
A hurricane acting on a 10 m2 wall creates a force equal to the weight of aprox. 750 kg.
