Pressure Threshold: The pressure above which the rupture disk breaks to vent the liquid to atmosphere.
Pressure Drop (Typical): Pressure drop corresponding to the typical flow.
Flow (Typical): This is a typical (positive) flow through the orifice or valve.
Elevation: Elevation at centroid of junctions, valves, and pumps; the ground elevation at tanks; the hydraulic grade at reservoirs.
Trace (Initial): Specify the initial trace amount at the current location.
Zone: Specify the zone for the element.
Concentration (Initial): Specify the initial concentration for the global concentration at the selected element.
Is Constituent Source?: If true then the selected node can inject a set concentration of the global constituent into the system.
Pattern (Constituent): Specify the pattern which dictates how the injected constituent concentration varies over time.
Constituent Source Type: Choices: Concentration, Flow Paced Booster, Setpoint Booster, Mass Booster
Concentration (Base): This data field allows you to specify the corresponding constituent concentration at this node over time.
