Study of methods for constructing a flow velocity profile in a small diameter pipe

This research paper describes the results of measuring the air velocity profile in a small-diameter pipe using different methods, namely mathematical modeling with the help of specialized software, measurement by a portable anemometer, as well as using a diffmanometer with a Pitot-Prandtl tube. The obtained results are shown in graphical and analytical form and allow to draw a conclusion about the suitability of the methods and their comparability in engineering calculations.
