Reported here is the experimental study in the pipe line element T-junction. The velocity fields were measured by PIV method with 3-camera alignment. This alignment makes accessible T-junction areas covered by image distortions and refraction irregularities in drilled glass block. Four basic connection regimes are studied with flow ratios into inlet branches in turn. Flow field is described with a numerical vector maps and presented as scalar maps with streamlines. Velocity profiles in the inlet and outlet branches are generated. Visualizations of the flow with streamlines and vector fields provide the basic characteristic of flows mixing, separations, vorticities etc. Analyzed datasets are used for evaluation and verification of numerical models.
