Orifice - ISO5167: 2003

Finds gas flow rate, orifice diameter and differential pressure in accordance with this standard. The volume flow rate at line conditions and standard conditions are found along with the energy and mass flow rates using line density, standard density and calorific value (heating value).

FLOWSOLV® V5 Pro packages contain ISO5167 calculations for 1980, 1991, 1997 and 2003. FLOWSOLV® V5 Essentials packages contain the 1991 ISO5167 calculation.
