6. Calculation of a flowmeter with depressurizing element
6.1 Available data
Over the last century, many experimenters have measured discharge coefficients. of various depressant organs. The data were first collected in tables, then smoothed out in the form of empirical relationships that could be processed by desktop numerical calculators, then by microcomputers; these relationships are therefore evolving, and the formulation due to Stolz, used since 1980 for diaphragms, is tending to become obsolete in favor of the Reader-Harris/Gallagher equation.
