Measurement of Gas Flow by Means of Critical Flow Venturis and Critical Flow Nozzles
Description
This Standard applies to the steady flow of single-phase gases and deals with devices for which direct calibration experiments have been made.
Standard applies only steady flow single-phase gases deals devices direct calibration experiments made, sufficient number quantity enable inherent systems applications based results coefficients given certain predictable limits uncertainty. critical venturi nozzles dealt can used within specified, example nozzle throat inlet diameter ratio reynolds number. specifies geometry method use (installation operating conditions) inserted system determine mass rate gas flowing system. also gives necessary information calculating associated critical. exists maximum possible existing upstream conditions. choked conditions, average velocity closely approximates local sonic velocity. cases which: (a) pipeline circular cross section; (b) assumed large space nozzle.
