Tuulikuormalaskuri

Tuulen voima pinnalle nopeuden ja vastuskertoimen perusteella.

Johdanto

Wind Load Calculator — Wind force on a surface from speed & drag coefficient. Enter Wind speed (mph), Drag coefficient, Surface area (ft²) to get an instant, accurate result.

Kaava

Simplified wind force: F = 0.00256 × V² × drag coefficient × area, where V is wind speed in mph. The 0.00256 constant is the standard velocity-pressure coefficient used in simplified wind-pressure formulas (derived from air density) when speed is in mph and pressure is in psf.

Vaihe vaiheelta

  1. Enter the Wind speed (mph).
  2. Enter the Drag coefficient.
  3. Enter the Surface area (ft²).
  4. Click Calculate to see your result instantly.

Käytännön esimerkki

Example: With Wind speed (mph) = 100, Drag coefficient = 1.2, Surface area (ft²) = 50, the Wind Load Calculator gives Force Lb: 1536.

Usein Kysytyt Kysymykset

Is this a full ASCE 7 wind load calculation?
No, this is a simplified velocity-pressure estimate — it does not include the exposure category, gust factors, and topographic adjustments required by the full ASCE 7 methodology.
What is the drag coefficient?
It reflects how much the shape of a surface resists or channels wind — flat walls typically use values around 1.2-2.0 depending on aspect ratio; consult ASCE 7 tables for precise values.
Should this be used for structural design?
No — treat it as a rough planning estimate only; final wind load design must be verified by a structural engineer against your local code.
What inputs does the Wind Load Calculator need?
You'll need to provide: Wind speed (mph), Drag coefficient, Surface area (ft²). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Wind Load Calculator?
The Wind Load Calculator applies the formula exactly as calculated — Simplified wind force: F = 0.00256 × V² × drag coefficient × area, where V is wind speed in mph. The 0.00256 constant is the standard velocity-pressure coefficient used in simplified wind-pressure formulas (derived from air density) when speed is in mph and pressure is in psf. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Wind Load Calculator free to use?
Yes, the Wind Load Calculator is completely free, requires no signup, and runs instantly in your browser.

Tietoa: Tuulikuormalaskuri

The Wind Load Calculator uses a real, verifiable formula — Simplified wind force: F = 0.00256 × V² × drag coefficient × area, where V is wind speed in mph. The 0.00256 constant is the standard velocity-pressure coefficient used in simplified wind-pressure formulas (derived from air density) when speed is in mph and pressure is in psf. — so results are accurate every time, not an approximation.
