ESDU 81039 provides basic data for use in the calculation of pressure losses for incompressible flow (generally liquid flow) in ducts containing orifice plates, perforated plates and thick orifice plates or in the determination of a suitable geometry for a...
This part of SAE J968 specifies the flow measuring system, including the fixture, to be used for flow testing the single hole orifice plates used in an orifice plate type nozzle and holder assembly (described in SAE J968/1) which is intended for testing and setting...
This standard is intended to cover only orifice plates designed for bolting between flanges, with flat or raised face, whose bolting dimensions are in accordance with one of the following ASA standards: B16b2 B16.1 B16b B16.5-1957 PURPOSE The purpose of this Standard is to establish:...
This Technical Note discusses the studies conducted by ESDU for the CFD validation of the predictions for pressure loss, discharge coefficient and flow characteristics in square-edged orifice plates. These studies used the validation data from the literature reviewed in ESDU TN 07007....
ESDU 82009 presents pressure loss and discharge coefficient data for subsonic compressible flow of gases through single, or multiple, sharp-edged orifices in thin or thick plates for flow rates up to choking. The mechanics of compressible flow through orifices are discussed...
This Technical Note provides a review of the data in the literature for incompressible flow through orifice plates published prior to 2006. These data include measurements and numerical predictions of the flow field and pressure distribution over the orifice test pipe, pressure...
