FOREWORD

This report analyzes four flange tap equations and three corner tap equations for the discharge coefficient for orifice plates. All of the equations analyzed are functions of Beta Ratios, Reynolds Number, and Line Size, and all data points were evaluated against each of the seven orifice flow coefficient equations described in more detail herein. The goals of the study were to review the data available to determine where any weak regions of the database may be, to provide a methodology for comparing the equations over a range of Reynolds Numbers, Line Sizes, and Beta Ratios, and to determine the performance of each equation in relationship to the appropriate available database of calibration data.
