The smaller circle represents a 4” vertical pipe, which intersects the effective region. The

when the pipe is vertical. Thus smaller pipe diameters can lead to a variety of different
geometries which would each require a separate calibration.
An alternative condition is shown in the next diagram where the side pocket is extended
until it passes completely through the effective region producing a “core”:
