Abstract: When flow calibrating a head class meter to establish its discharge coefficient, measurement of the fluctuating differential pressure has caused the largest uncertainty. With conventional techniques, ...

Abstract: Today, technical experts in Europe and the U.S. are debating the merits of conducting new orifice flowmeter tests, establishing the effects of upstream disturbance and conducting other programs ...

Abstract: An experimental program was undertaken to evaluate orifice flow coefficient variations with changes in plate concentricity. The tests were conducted on four Beta ratio orifice plates, ranging ...

Abstract: Prediction of orifice and flow nozzle coefficients from their dimensions is a matter of major concern. In the mid 1930’s, laboratory flow coefficient data were obtained for flange top orifices ...

Abstract: An approximate integral method of analysis is developed for unsteady laminar boundary layer flows. The case of a flat plate in a free stream with small harmonic velocity oscillations about a ...

Abstract: A theoretical model of a turbine meter, incorporating fewer restrictions than previously available models, is analyzed from both the momentum and airfoil viewpoints. The two resulting equations ...
