| Abstract: | The pressure of the fluid inside the perforated catch-pipe will be decrease ceaselessly along the prolonged axis due to the friction of pipe wall and the increase of velocity of fluid. The dimensionless relationships between the variables inside the perforated catch-pipe have been deduced on the basis of hydraulic principle in this paper. Also the hydraulic design process of the perforated catch-pipe with variable aperture was given. |
