Performance of NBS Cryogenic Flow Research Facility
The historical background and design of the Cryogenic Flow Research Facility have been given previously by Dean et al. . This report describes the present status of knowledge with respect to performing cryogenic flow measurements after a year of operation of the facility. The sources of error presented here details just the contribution of the flow facility itself to the uncertainty of flow measurements. Subsequent reports will deal with the problems and uncertainties in using the facility in research measurements and in evaluation of flowmeters. The uncertainties given here are limits to the discrimination possible in these subsequent investigations.
