Hydraulic Grade (Initial Start): The start node hydraulic grade elevation at the beginning of the transient simulation.Flow (Initial): A value corresponding to flow in the pipe at the beginning of the transient simulation.pressure wave) moves through the fluid in the pipe. Wave Speed: The speed with which a disturbance (i.e.Installation Year: Specify the install year of the element.Zone: Specify the zone for the element.Is available if the global constituent is set to zero order. Wall Reaction Rate (Zero Order): Zero order coefficient defining the rate at which a substance reacts with the wall of a pipe.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.
