What is true about the coverage uniformity of rotating sprinklers compared to fixed spray sprinklers?

• A. Rotating sprinklers have less uniform coverage
• B. Rotating sprinklers have more uniform coverage
• C. Both types have equal coverage uniformity
• D. Neither type can achieve uniform coverage

Answer: (B)

Rotating sprinklers are designed to deliver water in a more uniform manner compared to fixed spray sprinklers. This improved uniformity is achieved through their rotational operation, which allows them to cover a larger area with a consistent application rate. As the rotating head moves, it creates overlapping streams of water that help reduce dry or overly wet spots in the landscape.

In contrast, fixed spray sprinklers often have a more concentrated and instantaneous application, which can lead to uneven coverage, particularly in areas where wind or pressure variations affect water distribution. The precise mechanical movement of rotating sprinklers helps distribute water evenly across a desired area, thus promoting more efficient water use and reducing waste. This characteristic is especially beneficial in water-efficient landscaping practices, as it helps ensure that plants receive the necessary moisture without excess runoff or pooling.
