A 1.5-inch groundwater line may be suitable for field irrigation, depending on factors such as the size of the farm, the type of crops being grown, and the irrigation system required.

Here are some considerations for irrigating fields with a 1.5-inch waterline:

Water Flow: Water flow through the 1.5" tubing will depend on factors such as water source pressure and tubing length. It is important to ensure that the flow rate is sufficient to meet the irrigation needs of the field. You may need to calculate flow requirements based on the number of sprinklers or drip emitters you plan to use.

Pressure loss: Water flowing through pipes encounters friction which causes pressure loss. Smaller pipe sizes generally have higher friction losses than larger pipes. For longer distances, elevation changes, or if you plan to run multiple irrigation areas simultaneously, it is important to account for pressure loss and ensure that the water pressure at the end of the line is sufficient for proper irrigation.

Pump Capacity: If you are using a pump to supply water to your irrigation system, make sure it has enough capacity to provide the required flow and pressure for the 1.5 inch pipe. It is important to match pump capacity to the needs of the irrigation system to ensure efficient water distribution.

Irrigation System: Consider the type of irrigation system you plan to use, such as sprinklers or a drip system. Sprinklers generally require higher flow rates, while drip irrigation systems require lower flow rates. Make sure the 1.5” tubing can provide the necessary flow and pressure for your chosen system.

Expansion and future needs: Consider future expansion of your field and potential changes in irrigation needs. If you anticipate increasing the size of your irrigation system or growing more crops, it may be helpful to install larger pipes to accommodate future needs.

Application example of farmland irrigation using 1.5 inch groundwater pipeline:

Small vegetable farms: For small vegetable farms, the use of 1.5-inch groundwater pipes can provide sufficient water flow and pressure to meet irrigation needs. The lines can be used with sprinkler irrigation systems or drip irrigation systems to ensure vegetable crops receive the right amount of water.

Orchard: For small and medium orchards, a 1.5-inch groundwater line is usually sufficient to meet irrigation needs. Pipelines can be arranged in a network or loop to supply water from the main water supply point to individual trees or rows of trees. This ensures an even distribution of water flow to meet the water needs of the fruit trees.

Flower Planting: In flower planting, using a 1.5-inch underground water line can provide sufficient water flow for flower beds or flower rows. A drip irrigation system or a micro-sprinkler irrigation system can be used to deliver water directly to the roots of the flowers to reduce water waste and evaporation.

Farm irrigation network: If there are multiple farmlands or irrigation areas that need water supply, the1.5-inch underground water pipe can be used as the main water supply pipeline, and then smaller branch pipelines are branched between each farmland. This network configuration allows for more flexibility in water supply, allowing the irrigation needs of each field to be controlled individually.

It should be noted that the above examples are for reference only, and in actual application, detailed evaluation and design should be carried out according to factors such as specific farmland size, crop type, soil conditions, and irrigation system requirements. It is best to consult a professional irrigation engineer or irrigation system supplier to ensure that an irrigation system is designed and installed to meet your specific needs.

For example:

Taking a farmland as an example, the farmland covers an area of about 10 mu and needs to be irrigated. After survey and design, it was decided to use 1.5-inch groundwater pipelines for farmland irrigation. During the construction process, topographical survey and pipeline layout design were carried out first, the pipelines were arranged along the field borders, and the water source was ensured to cover the entire farmland. Then, trench excavation and pipeline burial were carried out to ensure that the buried depth of the pipeline meets the requirements. Then, use special interface connectors to connect the pipes to ensure that the connections are tight and watertight. After the connections were made, a hydrostatic test was performed to confirm the proper functioning of the piping. Finally, warning signs and anti-corrosion coatings are set up to ensure the safety and durability of the pipeline.

So how many meters of 1.5-inch HDPE water pipes are needed for 10 acres of farmland?

To determine the number of 1.5-inch HDPE pipes required for 10 acres of land, the following factors need to be considered:

• Irrigation methods: Different irrigation methods have different requirements for water pipes. For example, if you use a sprinkler irrigation system, you need to install sprinklers and branch pipes, so you need more water pipes.

• Irrigation layout: The shape and layout of the field will also affect the number of hoses needed. If the farmland is in a regular rectangular shape, you can use a straight line arrangement to save the amount of water pipes used. But if the field shape is complex, requiring curved and branching pipe arrangements, more water pipes are required.
  

• Pipe connection: The pipe connection usually requires a certain length to connect different pipe sections, and connect joints, etc. This also needs to be taken into account in the calculation of the number of water pipes.
  

Typically, the approximate number of water pipes can be estimated based on the size of the field and the complexity of the layout. A simplified estimation method is provided below for reference:

Assuming the field is a regular rectangle and arranged in straight lines, the following formula can be used to estimate the number of pipes needed:

Total Pipe Length = Field Circumference + Main Pipe Length Inside Field

Based on the area of 10 mu of land, assuming that the farmland is a square with a side length of about 100 meters, the perimeter is 400 meters. At the same time, according to actual needs, a main pipeline may need to be installed inside the farmland, and the length can be estimated according to the actual situation, assuming it is 100 meters.

Total pipe length = 400m + 100m = 500m

Next, the length of each section of water pipe needs to be considered. In general, the standard length of HDPE water pipes is 6 meters or 12 meters, and the appropriate length should be selected according to the actual situation. Assuming a water pipe length of 6 meters, the number of water pipes required is:

Number of water pipes required = total pipe length / length of each water pipe

The number of water pipes required = 500 meters / 6 meters ≈ 83 pieces (rounded up)

Therefore, about 83 1.5-inch HDPE water pipes (each with a length of 6 meters) are needed to meet the irrigation needs of 10 acres of farmland. Please note that this is only a simplified estimate, and the actual situation may vary due to terrain, layout and specific requirements, it is recommended to carry out detailed design and calculation in actual engineering.
