Worked Solution & Example Answer:6.1 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 structure's ability to carry the heavy load of the irrigation system is primarily supported by:
- Triangulation/Truss Method: The use of triangular shapes adds strength and stability, effectively distributing the weight across the structure.
- Arched Design: The curved shape helps to evenly distribute load and withstand the forces acting on it.
- Steel Cables/Rods: Utilizing robust materials like steel contributes to the overall strength, providing additional support.
Step 2
Suggest ONE possible cause of sprinkler nozzle blockage and give a solution to the problem.
Answer
A possible cause of sprinkler nozzle blockage could be:
- Sand/Fertilizer Particles: These can accumulate and block the nozzle.
Solution: A preventive measure is to install a proper filter in the system to catch debris before it reaches the nozzle.
Step 3
State THREE factors to consider when selecting a water pump for the centre pivot system.
Answer
- Water Source: Ensure that the pump is suitable for the type of water source available (e.g., well, surface water).
- Type of Pump: Select an appropriate pump type based on flow requirements and the characteristics of the water.
- Size: The pump must be appropriately sized to meet the irrigation demands without overworking or inefficient operation.
