Abstract:
Small sonic nozzles (throat diameter 0.28 4.48 mm) were tested in the gas flow standard system. This standard system is composed of two bell provers and 5 column piston provers, compressor, filters, and dehumidifier. The discharge coefficients of small sonic nozzles are obtained and correlated as a function of throat Reynolds numbers with 0.33 % uncertainty at a confidence level 95 %. The tested high Reynolds number was the lower limit of ISO 9300 specifications. The data are useful as data base for revision of ISO 9300.
