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 sludge 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 innerD(ND{~}sludge~,EN{~}PipeSpec~)/2
sludgepipe{~}outr~ \- the radius of the outer cylinder defined by outerradius(ND{~}sludge~)
