What is the speed of a vortex?

The speed of a vortex can vary significantly based on its size, strength, and the fluid dynamics involved. In general, the speed is highest at the center of the vortex and decreases outward. For example, in tornadoes, wind speeds can reach over 300 miles per hour, while in smaller vortices, like those in water or air, speeds can be much lower. The specific speed can often be calculated using principles from fluid dynamics, such as the conservation of angular momentum.
