General Program Information

Input Definitions

• origin is the center point of the outlet of the first sedimentation tank
• width~sed~ is the distance between the outlets of the sedimentation tanks or the width of the sedimentation tanks from the center line of the wall on either side of a tank
• lvltank~dim~ is a 3,1 matrix with the x,y,z dimensions of the tank
• Δ x is the distance in the x direction in a top view from the outlet of the first sedimentation tank (or the origin of the first pipe) to the outside wall of the leveling tank
• Δ y is the distance in the y direction in a top view from the outlet of the first sedimentation tank (or the origin of the first pipe) to the outside wall of the leveling tank
• Δ z is the distance in the z direction in a top view from the outlet of the first sedimentation tank (or the origin of the first pipe) to the bottom wall of the platform
• lvltank~thick~ is the thickness of the walls of the leveling tank
• thick~platform~ is the thickness of the platform
• R1 is the inner radius of the pipes leading to the leveling tank
• R~main~ is the inner radius of the effluent pipe
• H~main~ is the height of the effluent pipe (or the water level in the leveling tank)
• n is the number of sedimentation tanks
• disp is the displacement of the center of the pipes coming up into the leveling tanks from the inside wall of the tank

Notes

• All coordinates correspond to a top view.
• The floor of the leveling tank is at the same elevation as the top of the platform

Pipe Labeling

Step by Step Description

The Sed~eff~ program is composed of three scripts. The program will run Sedeff.script1 when n is 3, Sedeff.script2 when n is 4 and Sedeff.script3 when n is 5. Because the most common number of sedimentation tanks is three, the output of Sedeff.script1 will be described below.

Some points and values which will be used several times in the script are defined outside of the script so as to make it cleaner. These variables will be pseudo inputs for Sedeff.script1. They are listed below and will be described in greater detail further down.

• pipe2.origin, pipe3.origin, pipe4.origin, pipe5.origin, pipe6.origin, elbow1.origin, pipe7.origin, tank.origin, main.origin, origin, lvltank.dim, Δx, Δy, Δz, tank.thick, thick.platform, width.sed, R1, R.main, H.main, n, disp

layer1 - Creates a 'lvlpipe' layer for all of the pipes (except the "main" pipe) in the program

Pipe1 - Creates a pipe with an origin at the variable "origin". See Pipe Help for details on the pipe program.
