WebCoefficient of discharge for orifice flow can be calculated using Reader-Harris/Gallagher (1998) equation (ISO 5167): where is: β - diameter ratio d 1 /d 2 ; Re D - Reynolds number based on bigger diameter; d 1 - internal diameter (smaller); d 2 - internal diameter (larger); WebIf the standard selected is the 1998 or 2003 specification the Reader-Harris/Gallagher equation is used to calculate discharge coefficient. Expansibility Factor If the standard being used is the 1991 or 1998 specification then expansibility factor is calculated by:
WebThe U.S. gas industry uses the Reader-Harris/Gallagher (R-G) equation to calculate the discharge coefficient. The R-G equation was derived using a database of discharge coefficient measurements taken by flow laboratories around the world.
