How to Calculate Wind Loads From Wind Speeds
WebDec 14, 2024 · To calculate the force of a 5-mile-per-hour wind, first convert the wind speed to meters per second. Using an online converter shows that 5 mph equals 2.24 m/s. Filling … WebThe ratio of wind speed and shaft speed is called the anemometer factor, and it varies depending on the physical construction of the unit, typically ranging from 2 to 3. Wind speed is calculated as follows: Instantaneous Wind Speed = Anemometer Factor x Instantaneous Shaft Speed. Average Wind Speed = Anemometer Factor x (Number of Turns / Time) WebJun 19, 2024 · For example, if the wind speed is 70 mph, the wind pressure is 0.00256 x 702 = 12.5 psf. How do you calculate force applied by wind? Calculating Force Based on Wind Speed The mass of air hitting a surface then equals air density times area. The acceleration (a) equals the square of the wind speed in meters per second (m/s). melatonin and radiation therapy
