What does actual head pressure refer to?

• A. The pressure required for soil absorption
• B. The measured operating pressure at a sprinkler head
• C. The maximum pressure achievable in an irrigation system
• D. The difference between static and dynamic pressure

Answer: (B)

Actual head pressure specifically refers to the measured operating pressure at a sprinkler head. This value is crucial for the effective operation of an irrigation system because it directly influences the performance of the sprinklers, affecting factors like the distance the water is thrown and the uniformity of coverage across the area. In a well-designed irrigation system, the actual head pressure must be within the optimal range for the specific sprinkler type being used to ensure that each emitter delivers water effectively. This measurement is taken while the system is in operation, accounting for factors like friction loss and elevation differences, which can alter the pressure from what it might be at the source. Understanding actual head pressure is essential for selecting and positioning sprinklers, as it directly impacts how well the irrigation system delivers water to the landscape. Proper management of this pressure leads to better water efficiency and healthier plants.
