"This investigation has taken different orifice sizes (0.3005", 0.4000", 0.5045", 0.6015") and tested their flow characteristics when used in a 1" diameter pipe. Each orifice was initially placed in a fully eccentric position, that is the circumference of the orifice was placed tangent to the inside circumference of the pipe. Data was taken with the orifice eccentric to concentric in increments of 0.050".
Plots of flow coefficient versus Reynold's number were made for each position of the four orifices tested.
Empirical equations were developed for determining the flow coefficient of the various orifice sizes placed in any eccentric position.
It was also shown that the region near the fully eccentric position was just as stable as the region near the concentric position and is thus very capable of producing accurate flow measurement"--Abstract, page ii.
