I am currently working on an EPANET project realizing that I don’t understand how EPANET is calculating the flow in the pipes. So this is an example of what I mean.
Reporting time steps 1h unit CMH
I have a tank connected with a pipe coming from a FCV valve delivering constant 600 CMH. The outlet pipe takes a flow of about 1109 CMH except those time steps when the flow is zero.
The total takeout for the first 24 h is 23,326 from 24 to 48 it is 21,090 and from 48 till 72 it is 18,874. This totals to an amount of 63,290 CM for 72h. If I still add the amount usable in the tank it adds up to 63,494 CM. But actually it should not exceed 43,403 CM. Could someone explain me where the 20,090 CM are coming from? It would be highly appreciated!
