Unit Headloss defined for Pump and Valve in the GUI is not properly explained? #770

Refer to the discussion here.

  • The EPANET API (aka. EPANET Toolkit, or the dll) reports all the links total head-loss or "head-gain" as total heads (i.e., with units of meters or feet).

  • The EPANET GUI (the interface based in the exe file) reports the pumps and valves total head-loss or head-gain, (in meters or feet), but for the pipes it reports the unit headloss in units of m/km or, equivalently, of ft/1000ft.

But in the GUI, the pumps and valves total head-loss is lumped ( in meter) together with regular pipe unit headloss in units of m/km.

Is it possible to make the EPANet GUI clearer?

I'm doing some work over at OpenWaterAnalytics/epanet-gui to update the EPANET GUI to work with the latest features of EPANET.

The primary purpose is to make the GUI work with the future EPANET 2.3 and not to add new features, but where there is some easy opportunities to improve the interface without significant effort I've been merging in changes.

This applies for lots of features in SWMM that could work in EPANET as porting the code is sometimes simple.

Have you got an suggestions of how you think the problem be solved? Potentially either or both of these might work:

  1. Add both headloss and unit headloss
  2. Add support for a description section like SWMM and provide clarity on what the values represent

Potentially an admin could move this issue over to epanet-gui
