Design pressure in an irrigation system should not exceed what percentage of the static pressure?

• A. 70%
• B. 80%
• C. 90%
• D. 100%

Answer: (C)

The correct answer is that the design pressure in an irrigation system should not exceed 90% of the static pressure. This guideline is important for several reasons relating to the efficient and safe operation of irrigation systems. When the design pressure is set at 90% of the static pressure, it provides a safety margin that helps prevent structural failures within the system, such as pipe bursts or component damage. This is particularly crucial during times of peak demand when pressures can fluctuate due to varying flow rates. Additionally, maintaining the pressure below the full static pressure ensures that the irrigation system operates within optimal conditions, meaning that sprinklers and other irrigation devices can perform effectively without creating undue stress on their components. It also assists in reducing the likelihood of unintended leaks or losses in the system, which can lead to wasted water resources and increased operational costs. This limit also provides a balance between efficiency and safety, allowing for variations in conditions without risking the integrity of the entire irrigation infrastructure.
