Orifice Calculation 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).
