What is the precipitation rate of geared rotor nozzles?

0.05 - 1.0 inches per hour
0.1 - 1.5 inches per hour
0.2 - 2.0 inches per hour
0.3 - 1.8 inches per hour

The correct answer is: 0.1 - 1.5 inches per hour

The precipitation rate of geared rotor nozzles typically falls within the range of 0.1 to 1.5 inches per hour. This rate indicates how quickly water is applied to the landscape, which is crucial for effective irrigation design and management. Understanding this range is essential for auditors to ensure that irrigation systems are operating efficiently and that landscapes are receiving adequate moisture without leading to runoff or water waste. Geared rotors are designed to provide uniform coverage and are often used in larger areas due to their ability to project water over longer distances while maintaining a consistent flow. The chosen precipitation rate reflects both the hydraulic design of the nozzles and the intended applications, allowing irrigation professionals to select the right nozzle for the specific landscape conditions. In contrast, the other options reflect rates that are either too low or too high for geared rotors, making them less suitable for general applications compared to the selected range. Thus, the answer selected highlights the most accurate and practical range for geared rotor nozzles in landscape irrigation systems.
