      <abstract xml:lang="en" contentType="abstract">Measurements showing how the velocity profile of a highly turbulent air flow is laminarized by the soft hairy walls lining the pipe walls.The documented detailed but manual measurements were done in 1979, A Prandl pipe was used to determine the dynamic air pressure in sections along the pipe.  

The dataset was originally published in DiVA and moved to SND in 2024.</abstract>
      <abstract xml:lang="sv" contentType="abstract">Mätningar som visar hur hastighetsprofilen för ett mycket turbulent luftflöde laminariseras av de mjuka håriga väggarna som kantar rörväggarna. Mätningarna genomfördes 1979. Ett Prandl-rör användes för att bestämma det dynamiska lufttrycket i sektioner längs med rör.

Datasetet har ursprungligen publicerats i DiVA och flyttades över till SND 2024.</abstract>
