Is available if global constituent is set to first order.

Wall Reaction Rate (First Order): First order coefficient defining the rate at which a substance reacts with the wall of a pipe.Specify Local Wall Rate?: If true then a local wall reaction rate can be specified for the selected pipe.Bulk Reaction Rate (Local): Coefficient defining how rapidly a constituent grows or decays over time.Specify Local Bulk Reaction Rate?: If true than a local Bulk Reaction Rate can be specified for the pipe, otherwise the bulk reaction rate associated with selected constituent will govern.Status (Initial): Choices: Open, Closed.Minor Losses: List of all associated minor losses associated with the element, and can be used to generate the composite minor loss coefficient.Specify Local Minor Loss?: If true then the minor coefficient for the element is manually set, otherwise the value is derived from the minor loss library.Direction of flow is with the direction of the pipe. Has Check Valve?: Defines whether the pipe contains a check valve that limits flow to a single direction.Length (User Defined): A user defined pipe length that is not scaled from the underlying map dimensions.Has User Defined Length?: Allows the calculated scaled pipe lengths to be overridden with a user defined value.Darcy-Weisbach e: Darcy-Weisbach roughness height for the pipe wall.Hazen-Williams C: Hazen Williams C Factor.Diameter: Value represents the internal diameter of a circular pipe or four times the hydraulic radius for non-circular cross-sections.Hyperlinks: Associate one or more web link, photo, word processing document, or other file with this element.GIS-IDs: List of associated IDs on the GIS/data-source side.Notes: Additional information about this element.Label: Descriptive label for this element.ID: Unique identifier assigned to this element.
