orifice discharge

Improvement of the orifice discharge coefficient may not result in stability improvement as illustrated in one test series.

由一系列的试验说明，喷孔流量系数的改善并没有导致稳定性的改进。

The Development of Orifice Emitter of Model KD Series with Large Discharge

KD型大流量系列孔口滴头的研制

Characteristics of vertical sharp-edged orifice discharge(ⅲ) Effect of geometry on orifice discharge coefficient

垂直锐边孔口的自由出流特性（Ⅲ）孔几何形状对孔流系数的影响

The design of running system according to Large Orifice Discharge was used in practice.

根据大孔出流理论设计的浇注系统符合实际生产.

By means of formula of orifice come out, Bernoulli equation, formula of discharge along way and law of lose, general group of equation of discharge flow was established.

运用孔口出流公式、伯努力方程、沿途泄流公式及损失规律，建立了泄流管路的通用方程组。
