Study Notes
Philippine National Standard for Design of a Pressurized Irrigation System – Part A: Sprinkler Irrigation
- This standard outlines minimum requirements, criteria, and procedures for designing sprinkler irrigation systems, both periodic-move and continuous-move types.
- The standard references other relevant documents, including PNS/BAFS/PAES 217:2017, for irrigation water requirements.
- Key terms include average pressure, design pressure, distribution uniformity, irrigation period, and sprinkler irrigation.
- Sprinkler spacing is a crucial design factor, with guidelines provided for various wind speeds (e.g., up to 10 km/hr, 10-15 km/hr, above 15 km/hr).
- The recommended spacing is a percentage of the wetted diameter.
- Sprinkler systems (set systems, periodic-move systems, and continuous-move systems) are detailed with various operating principles (hand-move systems, side-roll systems, end-tow systems, centre-pivot systems, and linear-move systems).
- Materials for mainlines, submainlines, and laterals are covered in annex B.
- Several design criteria are presented that account for various factors like crop types, soil types, and irrigation water sources, and the recommended standards to adhere to.
- Data Requirements are detailed including topographic map specifications, land features, water resources data, and soil characteristics.
- Final design procedures are provided encompassing sprinkler spacing, system capacity, pipe size selection, total dynamic head, pump and power selection, etc.
- Formulas for various calculations are detailed to support design considerations such as net depth of water application (dnet), irrigation frequency (If), gross depth of water application (dgross) and preliminary system capacity (Qprelim).
- Annexes provide additional information on sprinkler types, recommended materials, and specific computations crucial for sprinkler system design.
