Niaboc67 said:For example the earthquake in Japan awhile back had the strength to capture a boat within it's pull. Yet the whirlpool created when someone pulls a plug on the bathtub is hardly any pull whatsoever.
Thanks
The velocity of a whirlpool can be measured by using a flow meter or by tracking the movement of objects or debris caught in the whirlpool. Another method is to use a stopwatch and measure the time it takes for a floating object to make one full rotation in the whirlpool.
The velocity of a whirlpool is typically measured in units of distance per time, such as meters per second (m/s) or feet per second (ft/s).
The strength of a whirlpool, or the force of its rotation, directly affects its velocity. The stronger the whirlpool, the faster the water will move and the higher the velocity will be.
Yes, the velocity of a whirlpool can be estimated without entering it by observing its size and shape. The bigger and deeper the whirlpool, the higher the velocity is likely to be. Additionally, the shape of the whirlpool can also give an indication of its velocity; a more narrow and tightly-spinning whirlpool will have a higher velocity compared to a wider and more loosely-spinning one.
There are various equations and formulas that can be used to calculate the velocity and strength of a whirlpool, such as the Bernoulli's equation, the Navier-Stokes equation, and the centrifugal force equation. However, these calculations can be complex and may require advanced mathematical knowledge and data about the specific whirlpool in question.
