WebSep 14, 2024 · This is state 1. Total pressure is thus 15 + 0 = 15 psi. Then somebody starts the fan and the wind speed increases to 100 mph. This is state 2. The dynamic pressure is now at 0.17 psi, as calculated in previous posts. This means that the new static pressure is now 15 psi - 0.17 psi = 14.83 psi, such that: WebSep 21, 2024 · Calculate 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 70 2 = 12.5 psf.
