Why is the water flow fast and slow, and what determines it?

There are reasons and ways to decide how the water flow is fast and slow, and I personally think that it is subject to itThe rotation of the Earththe impact of the production.

The earth is constantly rotating around the center of the earth's axis, and the direction of rotation is from west to east, and the deflection force is generated when the earth rotates. If you look closely, you can see that the right bank of the river is often washed out, but the left bank of the river flows slowly, so there is a lot of sediment accumulation. This has to do with the rotation of the Earth, to be precise, with the deflection forces that occur when the Earth rotates.

This phenomenon was first studied in detail by the French physicist Coriolis and is therefore also known as the "Coriolis force."

The results show that the horizontally moving objects (gases, liquids, solids) on the ground are affected by the rotation of the earth, and their direction of movement is deflected to the right in the northern hemisphere and to the left in the southern hemisphere, and the deflection force of the earth's rotation decreases with the decrease of geographical latitude, and the equatorial region.

The landslide force is very weak, but its effect can also be seen. To see the effect of the weakness, it is best to observe it on a large scale and over a long period of time. From satellite cloud imagery.

Look, all typhoons in the Northern Hemisphere rotate clockwise, which is the Coriolis force's "Trap."

Near the ground, the pressure in the center of the typhoon is particularly low, and the wind blows towards the center of the typhoon. After so much air ran to the center of the typhoon, it swirled along the eye wall and climbed to the top of the clouds.

So, the wind on the clouds blows outward. At this time, the reason why the downward sliding force shifts the direction of the air flow to the right is because the typhoon on the satellite image always rolls up the vortex.

The longer the length of the pendulum, the greater the speed of the pendulum, and the more significant the effect of the deflection. A large mass pendulum is relatively less susceptible to air resistance.

etc. To show the trajectory of the pendulum, there is a sand table underneath the pendulum. If the Earth is stationary, his swing draws a unique trajectory on the sand table, along which it keeps reciprocating until there is friction.

Lose all energy.

At the same time, the speed of the water flow is also affected by the topography, everyone knows that the water flows from a high place to the ground, if the drop is large, then the water flow will be faster.

Personally, I think it is determined by the topography and the rotation of the earth. Generally speaking, the water flows faster in places with large terrain differences. The geostrophic deflection force generated by the earth's rotation will also affect the water flow velocity, and the water flow is strong and fast in places with large geostrophic deflection force, which is also the reason for the formation of the "concave and convex bank" of the river.

1. It is related to the rotation of the earth;

2. It is related to the height of the drop of the river, which is based on the law of conservation of energy;

3. It is also related to the wind, the light wind will not be noticed, but the wind will also speed up the river when the wind is strong;

This has to do with the rotation of the Earth. The direction of the Earth's rotation is from west to east, and when the Earth rotates, it produces a deflection force, which is deviated to the right in the Northern Hemisphere, a phenomenon also known as the "Coriolis force".

Problem solving: Why do rivers go fast?

The large cross-section of the riverbed allows it to pass through the large flow of water, and the faster the flow rate of water increases.

There is a certain water flow difference, and the larger the flow difference of the water, the higher the water pressure, so the faster the flow rate of the water.

The riverbed is free of obstacles, the water flows smoothly, and the water flows faster.

What are the factors influencing river velocity?

Topography: The lower reaches of rivers are generally plains with relatively flat terrain and small river drops, resulting in a slowdown in water flow.

River width: The river channel is generally narrow in the upper reaches (V-shaped channel) and wider in the downstream (U-shaped channel), and the flat and wide channel disperses the river water volume and weakens the dynamics, resulting in a slower flow rate.

River volume: As the river flows through the middle reaches of the river, there may be high evaporation, which reduces the amount of water flowing downstream, resulting in a slowdown in the flow rate.

Sediment content: The river carries sediment from the upper and middle reaches to the lower reaches and begins to deposit, which raises the riverbed and reduces the drop between the downstream and the upper and middle reaches, resulting in a decrease in the flow velocity.

Wind speed: The magnitude of the wind speed directly affects the speed of the water flow.

Knowledge expansion: river hydrological characteristics: Flow: large (small) flow, large (small) seasonal variation of flow

Water level: The water level is large (small), and the water level changes large (small) in season

Flow Rate: Fast (slow) flow rate

Flood season: The flood season is long (short), and the flood season occurs in the summer (or other seasons).

Glacial period: There is (no) icing period, and the icing period is long (short).

Ling Xun: There is (none) Ling Xun.

Sediment content: large (small) sediment content

Hello, I am happy to serve you and give you the following answer: water flows fast. Reason:

1.High water flow: The higher the water flow, the faster the water flow.

2.Low resistance to water flow: The less resistance there is to flow, the faster the water will flow.

Workaround:1Increase water flow resistance:

The speed of the water flow can be reduced by increasing the resistance of the water flow, such as putting stones, sand, etc. in the water flow. 2.Reduced water flow:

Measure the flow of water: The first step is to measure the flow of water so that you can determine the speed of the water flow. 2.

Increase water flow resistance: You can put stones, sand, etc. in the water flow to increase the water flow resistance and reduce the water flow speed. 3.

1.Both water flow and resistance affect the speed of the water flow, so it is important to choose the right solution for the situation. 2.

When changing the path of the water flow, it is necessary to pay attention to the flow direction of the water flow to avoid problems such as water flow siltation.

Hello, it depends on the speed of the water flow. If the speed of the water is fast, the water will flow faster because it will flow out faster than the water that is left behind. However, if the flow of water is slow, the hand will be faster if there is less water, because it will accumulate less water than the water that flows more.

Hope it helps!!

The factors that affect the quality of drinking water mainly include the following:

1.The impact of water pollution.

Waterworks are based on source water, so the quality of the source water will affect the quality of the tap water to a large extent. According to the current water treatment and purification process of the water plant, it is fully capable of producing tap water that meets the standards. However, there are also many water purification plants with simple processes that are difficult to ensure the production of qualified tap water.

2.Effluent water quality status.

The pass rate of the factory water is not high, which will directly affect the quality of drinking water, which is mainly manifested in the fact that the factory water does not have chlorine or the amount of chlorine is not enough, and it may be a large number of microorganisms such as bacteria in the pipe network, affecting the water quality of the pipe network, and finally the water quality supplied to the user will be affected.

3.The impact of the water transmission and distribution network on water quality.

The water transmission and distribution pipeline network is an important part of the urban water supply system, and it is the purpose of the urban water supply enterprise to ensure the smooth water transmission of the pipeline network and ensure the user's requirements for water quantity, water pressure and water quality. The pipe network is seriously aged, damaged, and missing, and the microorganisms in the soil will seep into the pipe network with the groundwater during the intermittent water supply period, and the water supply quality is difficult to guarantee. For example, many cities in China laid pipelines before the 90s of the 20th century did not adopt internal and external anti-corrosion measures, and now the rust has been quite serious, becoming the cause of water quality accidents such as "red water" and "black water".

4.Impact of secondary water supply facilities.

The high-rise water in the city is provided with a water storage tank, which is distributed to the user's home through the water storage tank, but the secondary water supply lacks special maintenance and management, and the ventilation opening of the water tank is poorly sealed, which will lead to dust, insects, and rats entering the house, and bring certain harm to the safety of residents' life and drinking.
