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 due to its arched design, which distributes weight evenly and utilizes the triangulation or truss method for added stability. This design allows the system to withstand significant forces while minimizing stress on individual components.
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 mitigated by installing a filter in the system to catch debris before it reaches the nozzles.
Step 3
State THREE factors to consider when selecting a water pump for the system above.
Answer
- Water source: The availability and quality of water from the source must be assessed.
- Type of pump: Different pumps have various operational efficiencies and maintenance requirements.
- Size: The pump must be sized according to the water flow rate needed for the irrigation system.
