Hello
I want know if i put ink point in water cup .. How i can describe ink point
motion ??

Of course, gravity complicates things... first try without gravity:)Integral said:In the simple case you would use a spherical polar coordinate system and assume uniformity in all directions to get a solution in terms of only r, the radial component.
Read the man's post:Integral said:Fluid dynamics would only come into play if the fluid were moving. For a drop of ink in still water you should be able to apply the http://en.wikipedia.org/wiki/Diffusion_equation" .

"... ink motion in water as liquied with liquied. i think itsnt linear motion and i think its kind of chaos phenomena..."
It is obvious he is looking for fluid dynamics.
Abofaisal2008 said:yes, i think diffusion
I quoted the OP's words about what he is looking for - not words that somebody else fed him.Integral said:As for what you quoted, what the heck does that mean?
DaveC426913 said:Are we reading the same thread?
I quoted the OP's words about what he is looking for - not words that somebody else fed him.
When asked to elaborate what he is looking for, the OP's own words are about fluids in motion, and chaos.
Really, read the thread from post #1. Note what the OP is saying as opposed to what others are thinking he's saying.

ok .. put ink in water glass and observe motion of ink its not linear motion and its like smoke motion

i think that if you are doing it simply then talking about Brownian motion
The purpose of observing ink points in water is to understand the motion of particles in a fluid. By observing the movement of ink particles in water, we can gain insights into the principles of fluid dynamics and how different factors such as viscosity and turbulence can affect the motion of particles.
Ink points move in water due to the random motion of water molecules. This is known as Brownian motion and it causes the ink particles to move in a zig-zag pattern. Additionally, the movement of ink points can also be influenced by factors such as temperature, concentration, and the size of the particles.
To observe ink points in water, you will need a container filled with water, ink, a light source (such as a flashlight), and a microscope or magnifying glass. The container should be transparent to allow for easier observation of the ink particles.
The motion of ink points in water can have real-world applications in fields such as biology, chemistry, and environmental science. Understanding how particles move in fluids can help us understand the behavior of cells, chemical reactions, and the movement of pollutants in water bodies.
Aside from temperature, concentration, and particle size, other factors that can affect the motion of ink points in water include the density of the fluid, the shape of the particles, and the presence of external forces such as gravity or electric fields. These factors can all contribute to the overall motion and behavior of particles in a fluid.
