![]() (x y) Addition, also known as summing or, more colloquially, “plus” is used to sum numbers together. This calculator is optimized for either desktop or mobile use, making it a portable powerhouse or a reliable at-the-desk tool.īasic operations: Even the most advanced scientific calculator needs the basics in order to be useful - here are the most commonly used and basic functions: With the inclusion of many different features, easy access to a wide variety of scientific constants. For example, a surface at 90° to the ground experience much more wind load than a 4 5 ∘ 45^\circ 4 5 ∘ roof pitch, even if the wind speed and surface area is the same.Ĭonsidering all these factors, the wind pressure calculator determines the dynamic pressure and the wind load:ĭynamic pressure = 0.This free, easy-to-use scientific calculator can be used for any of your calculation needs but it is specialized for usage by engineers and scientists. Under the assumption that the wind is always parallel to the horizon, we can calculate the effective surface from the total surface and the angle. ![]() The effective surface is the surface orthogonal to the wind direction. The wind load also depends on the effective surface area of your structure. If you live at a location with significantly different conditions, we recommend using the air density calculator to determine your air density and adapt the value in this calculator accordingly. These conditions are known as standard temperature and pressure (STP). In this calculator, we assume a default value of 1.225 k g / m 3 1.225~\mathrm 5 9 ∘ F at sea level. The air density is a function of humidity, temperature, and pressure. The air molecules colliding with an object create a dynamic pressure, depending on wind velocity and the air density. To calculate the precise force, we need to have more information about the wind and the structure: The force of air particles hitting a surface is known as the wind load on a specific structure. We've gotyour back with our windsurfing calculator and kiteboarding calculator. ![]() Or use it for some fun exercise like windsurfing or the even more challenging kitesurfing. So, you can make sure that an unstable roof, window, or sign threatens your loved ones and your property.Īnd maybe safe in the knowledge that the wind will not hurt you, you can make use of it and create sustainable, clean, and cheap energy with your very own wind turbine (visit wind turbine calculator, for more). But don't worry, this wind force calculator is here to help you to estimate the wind load exerted on any structure, depending on the wind speed and the structure's surface area. The excessive wind load on roofs collapses buildings and endangers lives. In 2019 alone, storms caused over $40 billion in damage and numerous power cuts. Erosion disassembles our constructions bit by bit, roofs collapse under the load of snow, and floods and fires can have your life's work undone in seconds.īut one of the most damaging elements is one which we direly rely on for our survival: air. Whenever humans erect a structure, an eternal battle is raged against nature to keep it standing. ![]()
