# How do you calculate PSF from wind speed?

## How do you calculate PSF from wind speed?

Wind Speed Conversion (MPH) Ie: if the wind speed is 70 mph, the wind pressure is 0.00256 x 702 = 12.5 psf.

How do you convert wind speed to PSI?

Unit Conversions Convert mph to meters per second (m/s) by multiplying the speed in mph by 0.447. This value is obtained by dividing the number of meters in 1 mile, 1609, by the number of seconds in 1 hour, 3600. Convert Newton per square meter (N/m^2) to psi by multiplying the pressure in N/m^2 by 0.000145.

How do you convert PSF to mph?

q= (V^2)/383.6 where q is the pressure in PSF and V is the velocity in mph. For Example, Speed of 100 mph gives 26.07 PSF.

### What is 20 psf wind load?

Wind load is the amount of live load that hurricane garage doors can handle. For example, a 20′ by 20′ non-insulated 22 gauge chain operated hurricane garage door weights about 1,600 pounds. A 20 psf wind load adds 4,800 pounds of load on the building jambs – that’s three times the roll up door weight!

What is psf wind?

The correlation between dynamic wind speed and static equivalent pressure is formulaic in nature. These values are calculated from the Ensewiler Formula, P = 0.00256 V^2, where V = Wind Velocity in MPH and P = the Differential Pressure across the window in Pounds per Square Foot (PSF). …

What is PSF wind load?

foot (psf). According to this formula, a structure meant to withstand 100-mph winds must be built to resist a wind pressure of 25.6 psf. Using the example of a flat section of a structure, the area – or length x width – can be set to 1 square foot, resulting in a wind load of 1 x 25.6 x 2 = 51.2 psf for a 100-mph wind.

## Is PSI the same as PSF?

A low pressure value in pounds force per square inch units is converted into pounds force per square foot in the following way: 1 psf = 47.8803 pascals (Pa) 1 psi = 6894.76 pascals (Pa)…psf pressure related products.

How is PSF calculated?

Input the home’s square footage. Push the “Equal” sign to perform the calculation. The displayed number is the home’s PSF. For example, if the home’s price is \$100,000 and the square footage is 2000, the price per square foot is \$50 (100,000/2000 = 50).

### What is the PSF for 100 mph wind speed?

For Example, Speed of 100 mph gives 26.07 PSF. Important Note: This is the wind pressure calculated for the Basic Speed. The actual pressure that operates on the building depends on many other factors, and may be much higher than this value.

How to calculate the wind speed in meters per hour?

Wind (m/s) = 0.2777778 × Wind (km/h) Wind (m/s) = 0.5144444 × Wind (kts) Where: Wind (kts) is the wind speed in knots, Wind (mph) is the wind speed in miles per hour, Wind (km/h) is the wind speed in kilometers per hour, Wind (m/s) is the wind speed in meters per second.

What is the wind speed of Beaufort force?

Wind Speed Comparison Chart Beaufort Force Description Wind Speed Wind Speed Wind Speed kts mph km/h m/s 0 Calm 0 0 0 1 Light Air 1-3 1-3 1-6 2 Light Breeze 4-6 4-7 7-11

## How are wind speed and static equivalent pressure related?

The correlation between dynamic wind speed and static equivalent pressure is formulaic in nature. Dynamic wind speeds at various locations in the United States are determined from wind speed maps in the ASCE/ SEI 7 document. These wind speed maps are based on the historical weather data and provide the maximum expected 3 second wind gust speed.
