Worked Solution & Example Answer:6.1.1 Explain the structure's ability to carry the heavy load of the irrigation system - NSC Agricultural Technology - Question 6 - 2022 - Paper 1
Step 1
Explain the structure's ability to carry the heavy load of the irrigation system.
Answer
The irrigation structure's ability to carry heavy loads is primarily supported by its arched design, which distributes weight effectively through triangulation. The use of steel cables and rods enhances the stability and strength of the structure, allowing it to withstand mechanical stress and external forces.
Step 2
Suggest ONE possible cause of sprinkler nozzle blockage and give a solution to the problem.
Answer
One possible cause of sprinkler nozzle blockage is the presence of sand or fertilizer particles. This issue can be mitigated by installing a filter in the irrigation system to prevent such materials from entering the nozzles.
Step 3
State THREE factors to consider when selecting a water pump for the system above.
Answer
When selecting a water pump for the centre pivot system, consider the following factors:
- Water source: Ensure the pump is compatible with the available water source.
- Type of pump: Select the appropriate type of pump (e.g., centrifugal, submersible) based on the system's needs.
- Size: The pump must be sized correctly to deliver adequate flow and pressure for effective irrigation.
