General Information

Input Definitions

Inputs Needed to Call the Sludge Pipe Function

• sludgepipe_origin - a 3 by 1 matrix with x,y,z positions corresponding to the point where the manifold will be drawn
• ND_sludge - the nominal diameter of the sludge waste pipe - from this we can find the actual inner diameter and actual outer diameter of the pipe based on the schedule of pipe being used.
• tank_length - the length of the tank
• orifice_rad - the radius of the orifice hole
• orifice_dist - the distance between successive orifices
• EN_PipeSpec

Pipe Database Functions

• sludepipe_inr - the radius of the inner cylinder defined by inner(ND_sludge,EN_PipeSpec)/2
• sludgepipe_outr - the radius of the outer cylinder defined by outerradius(ND_sludge)

Inputs Defined Within the Sludge Pipe Function

p1 =

• x : sludgepipe.origin₀
• y : sludgepipe.origin₁
• z : sludgepipe.origin₂

p2 =

• x : sludgepipe.origin₀
• y : sludgepipe.origin₁
• z : sludgepipe.origin₂ + tank_length - orifice_dist

p3 =

• x : sludgepipe.origin₀
• y : sludgepipe.origin₁ + sludgepipe_outr + zc
• z : sludgepipe.origin₂ + tank_length - orific_dist

p4 =

• x : sludgepipe.origin₁ + sludgepipe_outr + zc
• y : sludgepipe.origin₂ + tank_length - orifice_dist
• z : sludgepipe.origin₀

p5 =

• x : sludgepipe.origin₀
• y : sludgepipe.origin₁ - sludgepipe_outr

p6 =

• x : sludgepipe.origin₀ + rad_hole + zc
• y : sludgepipe.origin₁ + sludgepipe_outr + 2*zc

p7 =

• x : sludgepipe.origin₀ - rad_hole - zc
• y : sludgepipe.origin₁ - zc

ND = ND_sludge

R1 = sludgepipe_outr

R2 = sludgepipe_inr

R3 = rad_hole

L = tank_length

n1 = floor( tank_length / orifice_dist )

n2 = 1

d1 = orifice_dist

win1 =

• x : sludgepipe.origin₀ - sludgepipe_outr
• y : sludgepipe.origin₁ - sludgepipe_outr
• z : sludgepipe.origin₂

win2 =

• x : sludgepipe.origin₀ + sludgepipe_outr
• y : sludgepipe.origin₁ + sludgepipe_outr + zc
• z : sludgepipe.origin₂

EN = EN_PipeSpec

Note: zc corresponds to the zoom constant used within AutoCAD and created in the basics file that is referenced by the pipe program.

Technical Program Outline

Note: All coordinates are referenced in top view in the program unless otherwise specified

pipe1 - using the pipe function draws a pipe (from the pipe program) with no zoom

zoom_win - zooms on a window space

cylinder3 - is to draw a cylinder for orifice purpose

viewrightside - change view to viewrightside

array1 - draw starting at point p1, n1 -- as many rows as the tank length/orifice dist, n2 - 1 and provide orifice distance as the next draw point for the cylinder

subtract2 - subtract unneeded portion of the cylinders
