Title (EN) METHOD OF DETERMINING END MEMBER CONCENTRATIONS
(FR) PROCÉDÉ POUR DÉTERMINER DES CONCENTRATIONS D’ÉLÉMENTS D’EXTRÉMITÉ
Abstract:
(EN) A method of determining a concentration of a component in a flow from a single source or layer contributing to a total flow is described using the steps of repeatedly changing the relative flows from the source; and for each of the changed relative flows determining the combined flow rate and a total concentration of the component of the total flow until sufficient data points are collected to solving a system of mass balance equations representing the flow of the component from each source at each of the changed flow rates.
(FR) L’invention concerne un procédé pour déterminer la concentration d’un  composant dans un écoulement provenant d’une source ou d’une couche unique contribuant à un écoulement global. Ledit procédé comprend les étapes suivantes : changement répété des écoulements relatifs provenant de la source ; et détermination, pour chacun des écoulements relatifs changés, du débit combiné et de la concentration totale du composant de l’écoulement global jusqu’à ce que suffisamment de points de données soient collectés pour résoudre un système d’équations d’équilibre de masse représentant l’écoulement du composant provenant de chaque source à chacun des débits changés.
