What is the precipitation rate of impact rotor nozzles?

0.1 - 1.0 inches per hour
0.2 - 1.2 inches per hour
0.1 - 1.5 inches per hour
0.3 - 2.0 inches per hour

The correct answer is: 0.1 - 1.5 inches per hour

Impact rotor nozzles typically have a precipitation rate that can vary based on several factors including the design of the nozzle, the pressure at which it operates, and the spacing of the sprinklers. The range of 0.1 - 1.5 inches per hour for the precipitation rate of impact rotor nozzles is a common industry standard. This range reflects the efficient performance of these nozzles under various conditions, allowing them to apply water at a rate that is suitable for many types of landscapes while minimizing runoff and ensuring adequate soil absorption. It's noteworthy that the lower and upper bounds of this range accommodate both light and heavy applications in different irrigation scenarios. Such flexibility is necessary in irrigation practices because different plants and soil types have varying water needs. Understanding this precipitation rate is crucial for landscape irrigation auditors as it assists them in designing irrigation systems that deliver water effectively without wastage or inefficiency.
