According to hydraulic principle, the change of efficient water head, discharge coefficient and discharge of orifice along porous pipes have been discussed and checked by experiments in this paper.
The first orifice plate 3 and the second orifice plate 6 are separated from each other in the liquid discharge direction of the discharge head 10 and disposed opposite to each other.
第一孔板(3)和第二孔板(6)沿着排放头(10)的液体排放方向彼此分开并且彼此相对地设置。

Three layers network topology is adopted. The input variables are water pressure, diameter of orifice, diameter of abrasive particles, flow rate of abrasive and feed rate of cutting head respectively.
