D) Creating a water tank and piping system. For plant systems
      No matter what kind of water we choose. All have different advantages and disadvantages. The author tells you that. At first, customers often. Before that. 
Need to drill a well. The pump is high pressure high water pump into the water supply system, single ponds can be used to use the farm or the system alone, but only to see.
Budget from the price estimate, then it must change. Because of the large pump design. Pumping from deep wells. Then compressed into the whole pipe system. It requires enormous energy.
And the equipment to catch sunlight converted into high-power electricity, and even more to drive a large motor with it. I also need to convert DC power. (DC.) From the solar panel. Come inverter
To convert to AC (AC) to drive motor of the pump. To pump water The bottom of the well is about 25-80 m from the surface when it comes up on the surface, it must be.
The outlet is a small outlet, such as water holes, droplets, dripping water, or even drive large sprinklers, which have to invest in a large number of solar cells and need to.
The time for the clouds to cover the sun. Or maybe a battery to come with.
 
   In view of the author. When reviewing how to water the plants to be cultivated. As mentioned in previous chapters. Since the selection to buy land. In the absence of natural water resources, we can
Create a water source in your own land by digging a pond or pond.
1) Choose a dig. Or create surface water by digging ponds or ponds. 
2) If the pool is not found water or water, we will choose to drilled wells. Is next
3) In groundwater, there are iron ore and other minerals such as calcium or limestone.
4) There should be groundwater. Sedimentation about 1-2 days before using to plant vegetables. To reduce the amount of minerals. To have an impact To plant
  Care should be taken to determine the irrigation characteristics, water content and the appropriate watering interval for the crops we will be cultivating.
And invent. And many different tools and devices. But in today's drip system. It is the most popular system. In terms of efficiency and use.
Water well And save labor for watering plants. It can also be used drip irrigation, fertilizers and drugs to plants effectively. And not waste Drip system also uses low pressure.
Less than 2.0 bars or less, just let the water have a higher level than the end of the pipe, where drip water can work.
     Water retention for use in watering plants. We have to have a water container. The size of the capacity. 
Will be large or small. It depends on the number of drops we need to use. Some farmers use it.
How to walk the pipe to the garden. Then drop the water to the plants that are planted. And will use the pump.
Pump water into the system. Until the root of the plant. The water as needed will stop the pump.
    But some plants. Not suitable for watering during sunshine. Which farm or garden to use.
Pump Direct sunlight, which only works during sunlight.
" Water tank "
     "Water tank" in the drip system is used in a variety of formats. Some of you use a bottle of salt water to hang.
To the tree Then let the water gradually drip down to the base or root of the plant look similar to the power.
Salt water plant Some use a 50 liter plastic tank of 100 liters to a 200 liter tank as it will find.
Available at economical rates.
 We may call a drip system from a bottle of brine, a soft drink, and a small tank, "tiny drip system."
Because there are many people who have seen a bottle of salt water. And then adapted to the way the plants. With drip system
Small, well, try to find information from google will find a lot of interesting ways.
  Planting "water" is the main factor. Watering plants in small areas. It can be used for human labor.
To water plants. But in a large farming area. Need water in sufficient quantities. And cost
In terms of high labor, and now labor is more rare than water.
  Farmer So look for ways to water the plants with less labor. And can handle enough water for.
Cultivated area Pumps, water pumps, water pipes, and so has played a large role in agriculture.
In modern times
   Investment decisions in the field of plant irrigation. It must be considered in the selection. To make a little investment
And most beneficial. And then there are expenses as a result. Like electricity Fuel costs if used.
The pump is powered by an engine.
   To work on the solar pump side of the author. At first, talked about the details.
To make the crop. Many of you are always attached to the image of a large farm irrigation system. I have seen in the first.
Imagine a large pump. Pumping lots of water Send them up on the hill or use a water pump.
Large pumping compressed into sprinkler system. What about the water system? 
  But some of you still do not know about the necessary information of the plant to grow it. How much water does the plant need?
Per day and watering time? It will be the best. Because in a large agricultural system. Or in large farms.
With funding And have a systematic management. Planning from experts in various fields. Design is complete.
The budget is unlimited. Like a banana garden. Some foreigners invest in some areas.
   It's simple. Think of the end to find the source. Should review the information in all aspects to complete.
Should start from a small scale. The result is good, it is gradually expanded into a multiplication of two times three times.
Yes that will be fulfilled. Should review several times before making a decision.
     In this chapter, the author discusses "the construction of water tanks and the laying of piping systems. For the plant irrigation system "must therefore
Discuss the basics before we can understand how much plants we can plant.
Using a pump driven by an electric motor. Or use a small propulsion engine. The investment budget.
Not much and can be mended. Or press the button to walk the pump at any time as we want.
  But for those who use electricity. And the engine oil for a long time to feel that it is so high costs.
It turns into a pumping system with solar cells. I have to understand that. The budget is higher than the old system.
Because we have to build a solar power plant. With our own investment. Will it be worth the long run?
In the future, the size of the budget will come from the power of the motor instead of the engine.
  And to understand it is deep. Solar pumping system There are two types.
1) Bring the solar cell to saturate the battery and then take out the electricity stored in the battery. 
With the pump, it has the advantage. Can open or close. Any time If there is enough electricity in the battery.
 The system is working normally. The battery still does not deteriorate. Distilled water is not dry
 But the budget is high. And care must be available in all areas to keep the system running normally.
2) Direct Solar Pumping System No battery
  This is the type that the authors produce. The reason is "reduce the investment budget" in terms of battery life.
No need to use an inverter. Converting electricity back and forth To lose And the author has used the system.
DC or 100% direct current (Pure Direct Current System), which is cheaper than the battery back up.
  But it will have the disadvantage that "it can only work in the sun."
The limitation is that the machine will pump only in sunlight. We need to find a way.
The direct pump can pump the maximum amount of water in the sun.
And some plants should not give water. Or water in the sun. Such as vegetables with stems.
The subtle is close to the ground. For example, Chinese kale lettuce, but fruits and perennials can be watered.
 "Drip system" and "small sprinkler system" are the most suitable irrigation systems.
For watering plants that can not be watered in sunlight. We can keep water.
Put in the tank and then open the dam. Pay to the drip system. And springer small in the afternoon.
Or evening 
  In the morning The land is not heated. We can use the pump. Pump water into the system.
Low pressure In the daytime, the sun was pouring up and stored in a storage tank. To plant trees in the evening.
  From the diagram above The author uses the Auto Cad program to describe another way of managing water by using natural energy: "gravitational force"
It is also a natural energy that we can use. Let's show the movie again, looking to the right is a pond or surface water. The author will always emphasize that.
We should have water on the surface. The area of ​​our own when we dig about 2-3 meters in some areas.
The water or the water, the water, and will be a place to store water in the rainy season. 
 
  The position of the pool Should be located where we will build a home. Or HQ For the following reasons:
1) We can bring the soil from the digging. Lean or reclaim as a hill for home. Just hiring a digger can start.
2) We should set up a pump near the house. And water tank Easy care near the ears near the eyes to prevent theft.
3) When the water tank is near We can distribute water to various points. With the opening of the dam. Do not go far or in the wilderness may be dangerous reptiles.
4), etc.
 Expand the layout again. When we dig into the soil. When the water is found. We set up near the water source. Then pumped up the tank. The distance to the pump can work to pump water.
Per hour than water delivery. The load is lighter and when the soil from the digging. Come on, or do a hump. Make a point that the water tank is higher than the area of ​​about 2-4 meters.
(Which depends on the condition of the ground. And the skill of the driver dug) and the concept of the project owner.
 
   When we pumped the tank up to 6 meters high, when combined with the height of the hump or hills we would have another 2 meters. When the tank was full, there would be pressure in the pipe system at  6 + 2 = 8 meters. 0.8 bars.
This is the pressure from the weight of water caused by gravity. Or atmospheric pressure Pressure does not reach the bar. We can be used in the drip system. Because of the nature of water or liquid.
Will flow from high levels. To low The same level. To stop the flow of water or liquid to reach each other, it will transfer to the same level to stop.
 
  Water that is trapped to a high level from the level of the "fictitious center" will be retained for its potential energy. When a flow occurs, the potential energy is converted into the kinetic energy of the dam. 
Then use the energy accumulated in the water to spin the rotor. electricity generator The same as the dam with hydropower. But our water level is only 8 meters. Open the water for a while. When the water level drops.
The pressure of water will be reduced. Until the tank empty. Or stop moving
 Cast a long time. To convince everyone to look at the energy of the water we can.
Pull us to work. There will be less than 1 bar. But if we can bring it to work.
This will be a tremendous benefit to me now. 
  Now let's see the tank before. What do we do with the raised water from the ground for 8 meters?
Some of you use the method. Set up a steel platform 6 meters high and then carry a 1000 liter water tank up to 2000 liters or more.
It is a popular way to do it. 
  1 liter of water will weigh 1 kg, so 1 cubic meter or 1000 liters of water will weigh 1 ton.
If we use 4,000 liters of 4 liters together, then 12,000 liters of steel or legs must support up to 12 tons.
Various variables are beginning to be elephant Surin. Need to pile or make foundation? Equipment price
How much will it cost to build or do it yourself?
 Left hand is a concrete tank of the company. This is the image of the temple Khao Khao. You take
The author has seen many works at the Korat. I also like the strength. And this price. (Installed at Buriram)
The news that if the Korat than. The price will be down. The author did not know the central material trade. Or that advertising costs, but that.
Good durability. The only way to do it is to negotiate the normal price offline as it is agreed.
  Let's take a picture of the rabbit as a process to create a tank. For those who are interested.
I'm going to do it, try to look at how to build yourself or hire him to be more suitable for us.
 No foundation pile. I would have to find a land position is not soft or liquid.
Looks from the picture, only the ground adjustment. Use a mortar to adjust the bottom of the tank. And put the iron.
    The water tank is a square octagonal height of 80 cm, height of 2.6 meters, up to 8 floors, height of 6.5 meters.
It can hold 28,800 liters of water or 28 cubic meters.
  The walls are 10 cm thick. The tank floor is poured with concrete, waterproof mortar and waterproofing.
  The location should be where the car can be reached.
  When the base is strong and stable. To gradually go up to the floor.
  The process is systematic and fully equipped.
    The height of 80 cm, 8 stories, total height of 6.5 meters.
      This unit has a water capacity of 29 cubic meters, 6.5 meters high. When the tank is full, the pressure is 0.65 bar.
It is a build. And create your own, depending on the suit and budget of each.
  When we have a water tank, a water tower, or a waterfall. When we accumulate water mass in the water tank when higher. It will accumulate energy in the water. The same as the accumulation of water.
In the dam When we open the water outlet, the potential energy is converted into kinetic energy. When moving or flowing Similar to the mass of water to spin.
The power generator for the dam is huge. When spinning the generator, it can work for a long time continuously.
    For the bucket we created. It's hard to work with the dam. If our tank is a tank, try cement. It can be up to about 5.4 meters tall.
This will give us a water pressure of 0.54 bars if the water is long distances. Water will flow to it. Until the water level of the source. And the level of pressure. Is the fi

 

l at the source tank.

The water level is higher than the destination. Water will flow to the destination at any time.
        For the water pressure of less than 1.0 bars to drive sprinkler mini sprinker or low pressure water delivery system. Can be used with drip irrigation systems.
Small and medium size and other applications in the next chapter. The current drip system has been developed to be easy to use, easy to install, and cheap.
Small area To a large area without limit. Both have a high water tank. And pump used to pump water into the system. Click here for details.
