Windage is a term used in aerodynamics, firearms ballistics, and automobiles that mainly relates to the effects of air (e.g., wind) on an object of interest. The term is also used for the similar effects of liquids, such as oil.
Please introduce links to this page from ; try the Find link tool for suggestions. ( February 2017 ) Because they are heat engines , steam turbines are subject to inefficiencies as they convert thermal energy in high-pressure steam to rotational kinetic energy in a shaft.
"Windage" as applied to British muzzle-loading ordnance referred to the difference between a gun's bore and the projectile's diameter, typically 0.1–0.2 inches (2.5–5.1 mm). This gap was necessary to allow the projectile to be rammed down the length of the barrel on loading.
Adjustable sight: Any aiming mechanism, usually iron sights, that allow the user to move the reticle up or down (elevation), and left or right (windage), in order to compensate for wind and distance. Ammunition or ammo : Can be described as anything that can be launched or thrown.
Flow visualization of wind speed contours around a house Wind engineering covers the aerodynamic effects of buildings Damaged wind turbines due to hurricane Maria. Wind engineering is a subset of mechanical engineering, structural engineering, meteorology, and applied physics that analyzes the effects of wind in the natural and the built environment and studies the possible damage ...
In most tropical cyclone basins, use of the satellite-based Dvorak technique is the primary method used to estimate a tropical cyclone's maximum sustained winds. [5] The extent of spiral banding and difference in temperature between the eye and eyewall is used within the technique to assign a maximum sustained wind and pressure. [6]
Because of the definition of pi, in a circle with a diameter of one there are 2000 π milliradians (≈ 6283.185 mrad) per full turn. In other words, one real milliradian covers just under 1 / 6283 of the circumference of a circle, which is the definition used by telescopic rifle sight manufacturers in reticles for stadiametric ...
The captain of a steam ship naturally chooses the shortest route to nearby destinations. Since a sailing ship is usually pushed by winds and currents, its captain must find a route where the wind will probably blow in the right direction.
