True or False: The precipitation rate is higher for a spray head than for a rotor head.

The statement is true because spray heads are designed to produce a finer water mist over a smaller area, which results in a higher precipitation rate compared to rotor heads. Spray heads typically apply water at a rate of 1 to 3 inches per hour, while rotor heads usually have a precipitation rate of about 0.4 to 1.0 inches per hour, as they deliver water in a more dispersed pattern that covers larger areas over a longer duration.

This difference in application is important in irrigation design, as it affects how quickly the water is absorbed by the soil and can prevent runoff or pooling. Understanding these rates is crucial for effective irrigation management, ensuring that different landscape areas receive appropriate water levels based on the types of heads used. For scenarios requiring rapid water delivery, such as flower beds or vegetable gardens, spray heads are the preferred choice.
