This pool acts like a river. Let’s Do Nature!

When people build dams — huge walls that block lakes and rivers — have to form a spillway, which is flooded with water.

The irrigation canal can be as simple as the way for water to flow over the surface of the dam, or more difficult, as the next step. In some cases, there is a large hole under the water (dry side) for the water to drain out like a water gun. This is how it works on Power Plant in Brazil. There is a file on good movie showing water coming out — it looks like a river in the sky, for real reason and river air.

But the coolest physics of this lost road is that the flow of water out of the pit mainly depends on the depth of the water behind the dam. As soon as water comes out of the tube, it is like a ball thrown instantly. Yes, you know what I’m going to do: I’ll use the residual water residue and leave the drainage system to measure the depth of the reservoir.

There is a real name for the relationship between water and its depth – it is called Torricelli’s Law. Imagine that you have a bucket full of water and have a hole drilled in the bottom. We can use physics to measure the flow of water as it comes out.

Let’s start by thinking about water changes in a very short time when water comes out. Here is the picture:

Looking up at the top of the bucket, the water comes down — even if it is just a little bit thick. It doesn’t matter how low the water gets; what we are interested in is the amount of this water, which I say is dm. In physics, we use “d” to represent the diversity of things, so that they can be just a small amount of water. This drop of water at the top means that the water has to go somewhere. In this case, it goes through the hole. The amount of running water should also be dm. (You must follow all the water.)

Now let’s consider this from a powerful perspective. The water is closed, so all energy must be doubled. There are two main types of thinking in this regard. First, there is the force of gravity (U_g = mgy). This is the force connected with the height of an object above Earth, and it depends on the height, mass, and gravity (g = 9.8 N / kg). The second type of energy is electrical energy (K = (1/2) mv²). These are forces that take mass and speed (v) object.
