Irrigation Association Exam Flashcards and Exam Questions
Question What is the standard maximum safe water velocity recommended for PVC irrigation mainlines to prevent water hammer and pipe damage?
Answer and Explanation The standard maximum safe velocity is 5 feet per second (fps). Keeping water velocity at or below this threshold reduces the risk of pressure surges (water hammer), which can fracture pipes and damage fittings when valves open or close rapidly. Start the Free Practice Test →
Question If a pressure gauge reads 50 PSI at the base of a hill, what will the approximate static pressure be at a sprinkler head located exactly 20 feet vertically above the gauge?
Answer and Explanation The static pressure will be approximately 41.34 PSI. Water loses 0.433 PSI for every foot of elevation gain. Therefore, 20 feet multiplied by 0.433 equals 8.66 PSI in elevation loss. Subtracting 8.66 from 50 PSI gives you 41.34 PSI. Review the Study Guide →
Question Which electrical component is responsible for receiving the low-voltage signal from the controller to physically open an automatic irrigation valve?
Answer and Explanation The solenoid. When the controller sends a 24-volt alternating current (VAC) signal to the valve, the solenoid creates an electromagnetic field that lifts a small plunger, altering the internal water pressure and allowing the valve diaphragm to open. Access Flashcards →
Question What term describes the rate at which water penetrates the surface of the soil, usually measured in inches per hour?
Answer and Explanation Infiltration rate. Knowing the soil's infiltration rate is critical; if your irrigation system applies water (precipitation rate) faster than the soil can absorb it, it will result in wasteful runoff and potential landscape erosion. Start the Free Practice Test →
