灌溉系统设计标准水源 1水必须运到现场在足够的压力和流量，提供最大的性能，如下图所示： 压力要求:- 55 psi工作压力在现场位置和海拔高度 - 40 PSI AT BASE OF SPRINKLER HEADFLOW REQUIREMENT - 22 GPM MAXIMUM FLOW RATE - 16 GPM MINIMUM FLOW RATEDIFFERENCES IN AVAILABLE FLOW AND OR PRESSURE WILL REQUIRE DESIGN CHANGES.2. WATER SERVICE LINE, WATER METER, BACKFLOW PREVENTION DEVICE, PRESSURE CONTROLS, CHECK VALVES,SURGE PROTECTION, ETC., AND PERFORMANCE OF THE WATER SOURCE ARE NOT A PART OF THESE DRAWINGS.HEAD LAY-OUT1. HEAD LAY-OUT AND SPACING IS BASED ON FIELD DIMENSIONS. ALL HEADS OF EACH ROW ARE EQUALLY SPACEDACROSS FIELD. ALL HEADS WITHIN A ROW ARE EQUALLY SPACED ALONG LENGTH OF FIELD. IN GENERAL HEADSPACING IS AS FOLLOWS: HEAD SPACING = 41.25, LATERAL SPACING = 40.2. HEAD AND LATERAL SPACING WILL VARY WITH DIMENSIONS OF FIELD.ALL SPRINKLERS AND NOZZLES SHOULD BE SELECTED BASED ON SPRINKLERPERFORMANCE, SPACING, AND ARC OF COVERAGE, AND ACCORDING TO FIELD DIMENSIONS.PERFORMANCE STATISTICS1.
