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 is designed with an arched design, which distributes weight effectively through triangulation. This architectural feature allows it to withstand significant loads while maintaining stability. Additionally, the use of steel cables or rods reinforces the framework, enhancing its ability to carry heavy components without risk of failure.
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 can be addressed by installing a filtration system that prevents these particles from entering the nozzle, ensuring a steady flow of water and maintaining the efficiency of the irrigation system.
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 irrigation system, consider the following factors:
- Water Source: Ensure the pump is compatible with the available water source, be it groundwater or surface water.
- Type of Pump: Choose the appropriate type of pump (submersible or surface) based on the installation requirements and efficiency needs.
- Size: The pump's size should be adequate to meet the irrigation demand, taking into account the area to be irrigated and the rate of water application.
