Good afternoon,
I'm modeling a situation with a discharge to atmosphere, but even after read the article "Modeling Reference - Discharge To Atmosphere [TN]" I have some doubts.Concerning the attached project, at the beginning I know that in normal conditions the debit required is 20l/s (typical flow), but how can I know the pressure drop if the pressure at the final pipe, in steady state, depends of the selected value for pressure drop? I used to consider a very low pressure drop (0,001bar) because I thought that in two close points the pressure would be similar, now I understand that it is not correct.Please, considering the attached file, can someone explain me how to proceed to estimate these values (flow (typical) and drop pressure (typical)) correctly? d2a.rar

Thank you very much for your answer Scott, Just one thing missing in my mind; the head loss units should not be "ft" and not "ft/s"?And if the "drop pressure" has to be in pressure units, how can I convert the head loss (ft) to pressure units (ex bars)?Because I can not consider the head loss units "ftH2O" right? Thank you very much for your help Best Regards Joao Henriques
