Input Definitions h5. Inputs Needed to Call the Inlet Slope Trapezoid Function origin - A 3*1 matrix with x,y,z positions corresponding to the point where the inlet slope will be drawn. Length - length of the slopes, generally the length of the sedimentation tank W{~}Sed~ - width of the sedimentation tank l{~}orifice~ - length of the opening that will allow inlet flow h{~}orifice~ - height of the opening that will allow inlet flow b{~}orifice~ - thick - thickness of the slopes n - number of orifices and sections, one section contains one orifice bigslope - slope of the inlet in degrees little slope - H{~}Trapezoid~ - h5.
