A design guide for pressure compensating spray stake systems, covering zone flow calculations, run length determination, and major component selection.
This document provides a step-by-step guide for designing a pressure compensating spray stake system. It begins by instructing users to determine the number of spray stakes that can operate simultaneously using a Zone Flow chart, ensuring water requirements do not exceed available supply. It also advises on balancing factors to determine the maximum length of a row or 'run' based on flow rates, pipe sizes, and inlet pressures.
| Minimum operating pressure | 22 psi |
|---|---|
| Maximum operating pressure | 55 psi |
| Recommended filtration mesh | 120 mesh |
The recommended filtration is 120 mesh.
The spray stake must be operated with a minimum of 22 psi.
