h3. Input Definitions
h5. 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 manifoldsludge pipe 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~ \- an enumerated pipe schedule which specifies a number which corresponds to a pipe schedule that states the amount of water pressure the pipe can handle before it fails. The pipe schedule affects the inner and outer diameter of the pipe.
h5. Inputs Found from Pipe Database Function
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~)

h1. Technical Program Outline
Note: All coordinates are referenced in top view in the program unless otherwise specified
*pipe1* \- using the [pipe function|AutoCAD Pipe Program] 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 |
