Wind Speed Formula:
From: | To: |
Definition: This calculator converts design pressure (in pounds per square foot) to equivalent wind speed (in miles per hour).
Purpose: It helps engineers and architects determine wind speeds corresponding to design pressure loads on structures.
The calculator uses the formula:
Where:
Explanation: The formula converts pressure exerted by wind into the equivalent wind speed that would produce that pressure.
Details: Accurate wind speed estimation is crucial for structural design, especially for buildings in hurricane-prone areas or for designing wind-resistant structures.
Tips: Enter the design pressure in pounds per square foot (psf). The value must be > 0.
Q1: What is design pressure?
A: Design pressure is the force per unit area exerted by wind on a structure, measured in pounds per square foot (psf).
Q2: Where does the 0.00256 constant come from?
A: It's derived from the basic wind pressure equation accounting for standard air density at sea level.
Q3: Does this account for different building heights?
A: No, this is a basic conversion. Actual design pressures vary with height, exposure, and other factors.
Q4: How accurate is this conversion?
A: It provides a basic estimate. For engineering purposes, consult relevant building codes and standards.
Q5: What's the typical design pressure range?
A: Residential buildings typically range from 15-30 psf, while high-rises may require 50+ psf in hurricane zones.
