Exploring the Hydrodynamic Paradox with Water Springs

In summary, the conversation discusses the concept of cohesion and adhesion in relation to water and how it affects the movement of water streams when there is horizontal and vertical hand movements. The person also mentions the Bernoulli equation and its potential impact on the movement of water.

Hello.

Have you ever seen this experiment?
OK, i know why does the watter flows without cover and does not flows with cover.
However, what about the springs? Why they get together with horizontal hand movement and separate with vertical hand movement?
Liquid always have the possible lowest energy. It is related?

Thank you very much.

Yes. It's about

versus
http://en.wikipedia.org/wiki/Adhesion

Cohesion makes the water stick together and minimize surface area. Adhesion makes the water stick to the fingers. The vertical finger moving horizontally diverts the streams horizontally so they collide and find a new local minimum surface area. The horizontal finger provides horizontal adhesion that pulls the streams apart. The horizontal deflection after collision with the horizontal finger might also play a role in separating the streams.

thank you very much
well, I thought about it and now I have some question. what about Bernoulli equation? ... namely hydrodynamic paradox. it makes underpressure near strings and can connect it together. how much does this affect?
 

What is the purpose of the water springs experiment?

The purpose of the water springs experiment is to observe and study the movement of water through different types of springs and determine what factors affect the flow rate and distance traveled by the water.

What materials are needed for the water springs experiment?

The materials needed for this experiment include various types of springs, a source of water, a ruler or measuring tape, and a stopwatch or timer. Optional materials such as food coloring and trays can also be used to enhance the visual observations.

How do you set up the water springs experiment?

To set up the experiment, first gather all the materials and choose the types of springs you want to test. Place the springs in a row on a flat surface, making sure they are securely held in place. Fill a container with water and place it at one end of the row. Use the ruler to measure and mark the starting point for each spring. Start the stopwatch or timer once the water is released onto the springs and record the distance traveled by each spring.

What are some possible variables to test in the water springs experiment?

Some possible variables to test in this experiment include the type and size of the springs, the angle at which the water is released onto the springs, the height of the water source, and the amount of water used. These variables can affect the flow rate and distance traveled by the water, providing valuable insights into the movement of water through springs.

How can the results of the water springs experiment be applied in real life?

The results of this experiment can be applied in various fields such as engineering, hydrology, and environmental science. Understanding the behavior of water through different types of springs can help in the design and maintenance of water systems, as well as in predicting and mitigating the impact of natural disasters such as floods. This experiment can also be used to educate and raise awareness about the importance of water conservation and management.
