The lines are close to parallel to each other, and close to parallel to the Reader-Harris/Gallagher (1998) Equation as found in ISO 5167-2:2003; the Equation with its uncertainty band is plotted in Figures 1A – 2B. Shifts are considered as simple increases in discharge coefficient without changing either d or β.

Webdischarge coefficient is the Reader-Harris/Gallagher (RG) equa-tion (1990, 1998), that is accepted as a gold standard in Amer-ican Gas Association (AGA) and American … WebSep 1, 2010 · Finally in 1998, Reader-Harris [7] developed a new equation derived from an analysis of the data collected by Kinghorn and the data used by Seidl. ISO adopted this equation in 2003 in ISO 5167-2:2003: (3) Y 1 = 1 − ( 0.351 + 0.256 β 4 + 0.93 β 8) { 1 − ( P 2 P 1) 1 / k }. 3. Mass flow rate calculations WebThe uncertainty of the orifice-plate discharge coefficient given by the Reader-Harris/Gallagher (1998) Equation has been calculated taking account of the uncertainty of the data on which it is based and of the variability in manufacture permitted by ISO 5167–2.
