General Program Information

Inputs Needed to Call the Manifold Function

manifold_origin - a 3 by 1 matrix with x,y,z positions corresponding to the point where the manifold will be drawn
ND_Manifold - the nominal diameter of the manifold 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.
orifice_rad - the radius of the orifice hole
tank_length - the length of the tank
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.
rad_hole - the radius of the orifice hole

Inputs Found in the Pipe Database Function

manifold_inr is the radius of the inner cylinder defined by innerD(ND_Manifold,EN_PipeSpec)/2
manifold_outr is the radius of the outer cylinder defined by outerradius(ND_Manifold)

Technical Program Outline

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

zoom_win - zooms on a window space

pipe1 - draws a pipe (from the pipe program)

cylinder1 - draws a cylinder with pipe_outr as radius

cylinder2 - draws a cylinder with pipe_inras radius

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

mirror1 - mirror the orifices on to the other side of the pipe at 2*tan(Pi)/3

subtract1 - subtract unneeded portion of the cylinders
