WebNov 12, 2024 · It is also called a weather vane. It spins in the wind, and shows us the direction from which the wind is coming. Well, typically an anemometer is also fitted with a wind vane to indicate the wind direction. Engineers design anemometers to measure wind speed for many situations other than for weather measurements. The fluid motion in a vortex creates a dynamic pressure (in addition to any hydrostatic pressure) that is lowest in the core region, closest to the axis, and increases as one moves away from it, in accordance with Bernoulli's principle. One can say that it is the gradient of this pressure that forces the fluid to … See more In fluid dynamics, a vortex (PL: vortices or vortexes) is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved.
