Question 2: In maintaining a drip irrigation system, what is the recommended procedure for cleaning clogged emitters?

Which action should you take?

Choose only one option

Use acid flushing to dissolve mineral deposits

Use a high-pressure water flush

Disassemble and scrub each emitter manually

Soak the emitters in chlorine solution

Question 3: Which of the following parameters is used to determine the irrigation water requirement (IWR) for a crop?

Which action should you take?

Choose only one option

Water delivery pressure and emitter spacing

Crop evapotranspiration (ET) and effective rainfall

Wind speed and soil compaction

Question 4: How do you determine the proper pump size when designing an irrigation system?

Which action should you take?

Choose only one option

Based on the water storage capacity of the reservoir

Based on the diameter of the irrigation pipes
