I couldn't figure out the approximate wind speed today.Calculation to determine wind pressure (how much force is being pushed per area) from wind speedI'll leave you with a note about "the It is not particularly difficult. I will post the calculation method and a written calculation of how much wind velocity has the ability to push per area.
Wind pressure (force pushed per area) is calculated from wind speed.
Outdoor installations, etc,How much is the structure affected by wind pushed by the wind speed?and the strength to withstand it.
Below are just a few brief notes on key points.
unit of wind speed
The speed at which air moves as wind. Units are.
- Units we commonly use: m/s (speed per second)
- International unit: kt (read as knot)
will be.The relationship between speed per second [m/s] and knots [kt] is as follows
- 1[m/s]=1.944[kt].
- 1[kt]=0.514[m/s].
(I'm not familiar with knots.)
What is wind pressure?
Wind pressure is, as the term implies, the pressure caused by wind, and is measured in units of Pa (Pascal)Wind pressure is expressed in terms of There are different types of wind pressure,Wind pressure types: total pressure (Pt), static pressure (Ps), dynamic pressure (Pv)will be.
Formula for determining wind pressure/pushing force from wind speed
In this article, we will use a simple calculation: how much wind pressure (force applied to be pushed) is calculated from the wind speed. If you want to obtain the exact pressure by fluid dynamics, you need to use the following formula.
or
PT: Total pressure [Pa],Ps: Static pressure [Pa],Pv: dynamic pressure [Pa],V: flow velocity [m/s],ρ: Density [kg/m^3]
However, this time, wind pressure (dynamic pressure) is obtained from no wind condition (wind pressure ”0” zero = static pressure ”0”).because of ...
Only this formula is used.
Density of air required for calculation
The calculation of how much wind pressure is applied from the wind speed requires the density (value) of the air. The density of air is as follows
