Running Water Quality Analysis

  • Browser > Data > Options > Quality:
    • Set parameter to Age
  • Open "Tank 8" properties (double click):
    • Set initial quality to 60 [60 hr old water before inflow]
  • Run
  • Graph > Time Series:
    • Add nodes to graph
    • Select parameter = Age

  • Browser > Data > Options > Quality:
    • Set parameter to Chemical
  • Browser > Data > Options > Reactions:
    • Global Bulk Coeff.: -1.0
  • Open Reservoir properties:
    • Set initial quality = 1 [1 mg/L Chlorine flow]
  • Open "Tank 8" properties:
    • Set initial quality to 0 [If left 60, then 60 mg/L before inflow]
  • Run
  • Graph > Time Series:
    • Add notes to graph
    • Select parameter = Chemical

Theory:

  • Around page 30 of PDF (junctions, reservoir, ..., major/minor loss, pump curve, ...)

Assignment:

  • Peak factor graph provided
  • Import layout into Epanet: View > Backdrop > Load [essentially background image]
  • Then add nodes at according positions
  • Only submit on Google Classroom
  • Deadline: Thursday, 12:20 PM
