4 Ways to Calculate Wind Load

May 25, 2020Calculate wind pressure. Wind pressure is given by the equation P = 0.00256 x V 2, where V is the speed of the wind in miles per hour (mph). The unit for wind pressure is pounds per square foot (psf). For example, if the wind speed is 70 mph, the wind pressure is 0.00256 x
