Orifice Plate Coefficient Study (1978)
Wayne A. Fling, Jr.
This project was started in August 1976 under the joint sponsorship of the API and AGA. The prime objective was to develop a new orifice coefficient equation capable of producing improved coefficient accuracy. The secondary objective was to use this new equation to update AGA Report #3 by making it more accurate and acceptable as an international method of fluid flow measurement for custody transfer.

Research Program to Develop an Archival Database of Low Reynolds Number Discharge Coefficients and Related Parameters for Sharp-edge Flange-tapped Orifice Meters (1984)
Charlie Britton, Steve Caldwell, Walt Seidl, & Taft Snowdon; Revised by Wayne Fling
The purpose of this research program was to experimentally determine the discharge coefficients for sharp-edge flange-tapped orifice plates at low Reynolds numbers.
