PR-60-50-R01 Orifice Meter Research Theoretical Study of Flow Through Concentric Orifices Author(s)Rodger Dowdell, Mason Wilson, Yu-Lin Chen, Raymond TeyssandierAuthoring InstitutionUnknownRelease Date October 1, 1972 Methods have been developed which will permit the calculation of flow patterns and discharge coefficients for concentric orifices of various diameter ratios when used for the measurement of incompressible flow in pipe lines. These methods are based on a three-dimensional, axi-symmetric model and ... More Info

WachelAuthoring InstitutionSouthwest Research InstituteRelease Date January 1, 1961 Describes the development and use of a tracer method to be used as a flow verification method. The method focused on cold air injection and hot wire detection, although some later work was done on infrared absorption techniques. Of specific interest in this document is how these techniques perform ... More Info
