For example, most of the U.S. is in Zone A with 86.6 mph wind, but coastal areas might lie in Zone B (100 mph) or Zone C (111.8 mph). Dynamic Pressure - Engineering ToolBox However, you can change it to a custom one that adapts to your wind's characteristics. Assume there is a 100 mph wind (146.67 fps) and air has a density of 0.075 lbs/ft3. For example, according to the Electronic Industries Alliance (EIA) most of the U.S. is in Zone A with 86.6 mph wind, but coastal areas might lie in Zone B (100 mph) or Zone C (111.8 mph). 3.l . Wind speed increases with structural height and is most unpredictable closer to the ground, because it is affected by interacting with things on the ground.
