Why is the operating pressure of spray heads important in irrigation design?

The operating pressure of spray heads is crucial in irrigation design primarily to ensure proper water distribution. Each type of spray head is designed to perform optimally at a specific pressure range, which allows for an even and consistent application of water across the target area. When the pressure is too low, spray heads may not project water adequately, leading to dry patches and uneven coverage. Conversely, if the pressure is too high, it can cause misting or excessive runoff, which not only wastes water but may also fail to deliver the necessary amount of water to the plants' root zones.

Maintaining the correct operating pressure is essential for achieving the desired irrigation outcomes, such as promoting healthy plant growth and optimizing water usage. Thus, the accuracy of water distribution based on the operating pressure directly influences the efficiency and effectiveness of the irrigation system.
