| Abstract: | The pressured sand filter has used in mini-irrigation cxtcnsivcly. Beginning with the filtermechanism this paper analyzes and intreduccs the law of contaAnnant Cuting off, head loss change andthe factors uf influence head loss. And the hydraulic formula for sand filter with quatz sand as filterlayer, used in mini-irrigation systems, was devcloPCd. |
