I am wondering if anyone here has tried to adapt epanet (water distribution net work analysis program) to analyize a gas flow net work e,g, a landfill gas collection system. Epanet uses H-W or D-W formulae to calculate pressure drop etc in a pipe net work. I expect the conversion from water to a gas application may be to too complicated as the epanet program wants (among other parameters) kinematic viscosity to be relative to that of water.

Anysuggestions?

I tried something.
In the linked zip file you can find the parts of code I modified and the epanet2.dll modified for gas flow, based on three different known public equations: Ferguson (formflag=FG), Renouard (formflag=RN), Spitzglass (formflag =SP). In order to be able to use the options added into dll, since I’m not able to modify/compile the Delphy code in the Epanet GUI, to use the options added I faked, temporary, the formflag parameter code so you can call the desired option. Substitute the dll and use the “D-W” option to call FG equation instead of DW. You cannot call other two equation from epanet gui at the moment.
