Water quality

reaction / decay

Track a reactive constituent (e.g. chlorine residual) through the network over an extended-period run, on top of the tank/demand time simulation — concentration and water age at every node vs time.

เมื่อไรจึงใช้
  • Disinfectant-residual studies (does chlorine survive to the far ends of the network?).
  • Water-age / residence-time and source-tracing questions in a distribution system.
ค่าที่ต้องกรอก
ค่าคำอธิบาย
Reaction modelFirst-order bulk/wall decay (or growth) rate for the constituent.
Source qualityInjected concentration at the source node(s).
EPS time baseRuns on the extended-period hydraulics — step and duration.
คำนวณอย่างไร

At each EPS step the hydraulics fix the flows; the constituent is transported along pipes and mixed at nodes, decaying by the reaction model. Concentration and age are reported per node over time.

ข้อควรระวัง
noteWater quality rides on the EPS engine — it needs a valid extended-period run (tanks, patterns), not a single steady solve.
