Today we use washing machines that moved back and forth, mixing water with small holes inside. The way this process works is the clothes inside, shaken, not mixed, and when the dirt falls, it is repelled by the clothes. Have you ever wondered why this works? Well, there are actually some mathematically equivalent terms that can be used to help us understand the fluid dynamics behind all of this. If you're interested, I can give an example in nature, where it happens in a similar way.
The beach has an area called a skew zone, and this is an area where the waves no longer break, but the water still pushes towards the side of the beach. Here you can walk, and your feet are wet, without reaching the waves. It turns out that in the skew zone and due to the fact that the waves hit each other as they roll back and back, quite a bit of sand and sediment is carried. It falls out of these very flat waves on the waves, precipitating more sand to the shore, even when other sand particles are eroded.
Think if you let the sand penetrate, just like the holes are inside your washing machine. In the warm-up zone on the beach, there is quite a lot of surface excitement, just like what happens inside your laundry room when the washing machine works. In many ways, the washing style of washing a washing machine, where you move your cramped back and forward over a grooved surface, or above a surface with very small holes, does the same thing as nature, and, of course, is similar to the process taking place inside the washing machine. We can prove it all mathematically.
We can actually use mathematical modeling to tell you about the best amount of water / soap ratio and the best amount of agitation you use to clean your clothes as efficiently as possible with a washboard. Have you ever wondered why new laundry machines are so energy efficient, and how can they be cleaned using less water? Well, scientists use the same basic mathematical computational equations and the same type of modeling that oceanographers use when trying to figure out the amount of sediment transport going to or from the beach in the skew zone.
If you are going to create something that cleans this way, or works in a similar way, then you need to know your math in the skew region. I hope you please consider all this and think about it.
