Orifice Plate Coefficients: corner#0.75
ISO 5167-2 orifice plate discharge coefficients (Cd) and flow measurement parameters per the Reader-Harris/Gallagher (1998) equation — corner taps, flange taps, and D-and-D/2 taps; beta ratio 0.10-0.75; Reynolds numbers 1e4-1e7
| tap beta | reynolds number | Cd (dimensionless) | approach velocity factor E (dimensionless) | beta ratio (dimensionless) | expansion factor Y (dimensionless) | permanent pressure loss pct (%) | pipe diameter in (inch) | tap type | uncertainty pct (%) |
