(Please note that all symbols, along with units, are defined in the nomenclature at the end of this paper.) This is much different than the thin-plate orifice geometry, for which the orifice length-to-diameter ratio (L/d) is in the range of 0.001 to 0.1.
In 1959, the American Society for Mechanical Engineers (ASME) produced an in-depth study for flow nozzles, venturis, thin-plate orifices, centrifugal meters, and pitot tubes, as well as open flow measurement devices and methods.
