• How to set Diameter units in MSX to meters

    G'day Team, Can someone please tell me how to change the MSX units for the pre-defined term 'D' from feet to meters? The MSX Manual states that Diameter can either be in Feet or Meters, however no-where does it say how to change it or what the unit…
  • Water Quality (Constituent) Analysis for a proposed water distribution network

    Greetings, I am looking for a standard procedure for determining the bulk reaction rate to undertake a water quality (constituent) analysis. I understand from the AWDM book and other literature that the procedure entails sampling water from the source…
  • Chlorine decay bulk reaction and wall reaction

    I'm trying to model chlorine decay in a distribution system. In constitution properties Can you please explain what (1-n) means in Bulk Reaction Rate? In help section of WaterGEMS under " Bulk Flow Reaction Rate" the eqn is having power (n-1). I…
  • How to include Mass Transfer Coefficient into MSX

    Hi Everyone, We're currently working on developing an MSX model for Chlorine Decay that can account for wall decay as a factor of Biofilm growth (thus removing the need to specify wall decay for specific pipes throughout the network). Unfortunately…
