The fivehole project is a series of python scripts that process the output from a five-hole probe measurement system and turn pressure data into velocities and flow angles.
The programs will be of use to you if you have a five-hole probe measurement system and want to get velocities and flow angles out.
The programs provide a limited but useful plotting capability with the and the http://biggles.sourceforge.net/>Biggles plotting software.
The fivehole programs currently use a robust and well tested algorithm for extracting flow measurements based on a 1979 paper by Treaster and Yocum - further details may be found in the extensive documentation.
