Sažetak

Akcenat se daje određivanju odgovarajućeg koeficijenta trenja i odabiru reprezentativne jednačine za protok prirodnog gasa u uslovima koji vladaju u mreži. U ovom je prikazan metod za hidrauličko rešenje gasne cevodne mreže sa prstenovima. Neodgovarajuća upotreba koeficijenta trenja, podjednako kao i upotreba neodgovarajuće jednačine za protok gasa može dovesti do netačnih konačnih rezultata. Uzrok ovih odstupanja je istražen na primeru, tako da se ovde daje poboljšana i tačnija procedura proračuna.
