The equation has been modified to reflect the more common units of the USC inch-pound system. 1.4 Expansion Factor Application WebThe equations provided in American and European national and industry standards and the various coefficients used to differ from each other even to the extent of using different combinations of correction factors, but many are now closely aligned and give identical results; in particular, they use the same Reader-Harris/Gallagher (1998 ... how to spot catfishing
C266 – AGA 3:1992 Orifice Plate Flow Calculation - Kelton
Flow rates through an orifice plate can be calculated without specifically calibrating the individual flowmeter so long as the construction and installation of the device complies with the stipulations of the relevant standard or handbook. The calculation takes account of the fluid and fluid conditions, the pipe size, the orifice size and the measured differential pressure; it also takes account of the coefficient of discharge of the orifice plate, which depends upon the orifice type a… WebThe Reader-Harris/Gallagher equation is considered an evolution of Stolz's work. While slightly different versions of the equation exist in A.G.A. Report No. 3 (API MPMS Chapter 14.3) and ISO 5167, the predictive results are within the experimental scatter.
