What is the difference between wind speed and wind pressure? Why can’t you just supply doors based on wind speed alone, such as a 120 mph door?
Wind speed is a velocity measured in miles per hour (mph). Wind pressure is a force measured in pounds per square foot (psf). Wind speed alone cannot be used to determine the wind pressures on a structure. Wind speed is one of many variables used in calculating design wind pressures that take into account the structure configuration and site location.
