Fluid dynamics (reology) according to the science of a constant volume and fixed form objects are solid objects. At the same time, the volume of liquid substances remains the same, but their shapes may change. The last criterion applies to cats: they can bend as you want to fill the container. However, if solid objects are applied to them, they may deform and fluids may have the properties of solid objects. It turns out that it is wrong to determine the fluid given above.
Experts use the number of Deborah (de) which are partially connected to the observation time (T). This number helps to indicate how liquid the object is. The smaller the number of deburus, the more liquid this object becomes. In addition, this number depends on the time of relaxation (τ), which is the time requiring liquid to adapt its shape.
To calculate the number of cats’ cats, you must determine the relief time. Genus, age and so on. Depending on, it varies from animal to animal. The shape of the environment or the box is the shape of the cat.
In the study published in Rheology Bulletin magazine in 2014, Mark Antoan Fardin of the Jacques Institute Monu said that the relaxation time of young adult cats was 1 second to 1 minute. This allows you to calculate the number of Deborah. For example, if the cat is squeezed into a small cardboard box for five seconds and is observed for a minute, de = 0.0833 … This is much less than 1, ie the cat shows liquid behavior.
Cats have other features that are characteristic of liquids. This is the limit of fluid (ie, like ketchup, you need to add a minimum amount of strength before the captain flow). Cats also adapt their bodies to the ship to fill. Another feature that occurs in cats and some fluids is high surface tension.
