渗灌管道单孔出流量,是指埋设在土壤中的渗灌管道上单个孔眼或单个灌水器单位时间内流出的水量,单位为L/h。它是渗灌工程规划设计的重要参数。本文就外导角冲头冲出的孔眼进行水头与流量的关系研究。渗灌管道单孔出流属薄壁小孔口出流,出流量的大小受出流条件的影响,出流条件不同,其出流量也不同。如土中出流和空气中出流、粗砂中出流
Single-hole infiltration pipe outlet flow, is buried in the soil infiltration pipe perforation of a single hole or a single emitter flow of water within a unit of time, in units of L / h. It is the infiltration irrigation project planning and design an important parameter. In this paper, the outer corner punch punched holes for the head and flow of the relationship. Single-hole infiltration pipe outlet is a thin-walled small hole outflow, the size of the flow under the influence of the outflow conditions, the outflow of different conditions, the outflow is also different. Such as soil outflow and air outflow, coarse sand outflow
