WebA crucial difference is that the pipe is of larger diameter ( $D=4\pm 0.01~\text {mm}$ ), and is shorter, with a length of $2500D$ . The pressure sensors monitor the flow at $250D$ and $2500D$ . The natural transition for this pipe is lower, being $Re\approx 3000$ . 3 Characteristics of puff turbulence cotton frock designGWT was used to identify the location of welds in straight run piping sections longer than 30’. To perform this type of inspection, a small amount of insulation is removed and a transducer ring is clamped around the pipe. This transducer transmits guided waves in both directions along the pipe.
