... to Reynolds numbers up to 1.5 × 10 7 . The discharge coefficients are measured for several tap diameters in Reynolds numbers ranging from 2.4 × 10 5 to 1.4 × 10 7 using the high Reynolds number calibration rig of the National Metrology Institute of Japan (NMIJ). Experimental results show that the discharge...

... rigid descriptive approach, it is necessary to be clear that calibration, the adjustment or tuning of free parameters in a model to fit the model output with experimental data, is not validation. (This distinction is emphasized in each of Refs. 4 5 6 7 , but earlier uses ( 8 ) often described...

A new calibration and data reduction...

... coefficients, while the throat diameter was used in computing the experimental discharge coefficients. The nine CFVs were calibrated in dry air using two NIST primary flow standards with expanded uncertainties of 0.05% and 0.09%, respectively. The calibration data span a Reynolds number range from 7.2 × 10 4...

A formal error analysis of the falling-ball method, an evaluation of the relative merits of calibration and individual measurements, and an analysis of reproducibility...

...S. P. Mahulikar; S. K. Sane This investigation analyzes the calibration nonlinearity of the ball-in-vortex flow-meter, designed to work on the principle of a rotating sphere in and due to a vortex flow. The comparison of this flow-meter reading with the standard flow-meter indicates the existence...

... sensitivity is increased by the power of the reflection coefficient. The measurement method is self-calibrating because the measurement of the acoustic impedance is independent of changes in the pulser voltage. Data are presented over a range of pulser voltages for two wall thicknesses. These results can...
