A step-by-step guide to calibrating a custom PIV system using PIVlab 1.2.
PIV settings: set interrogation area ([px] in both dimensions) to 24 and Step ([px] spacing between the centers of interrogation area) in both dimensions to 12
-0- frame (represented as -0-) is the moment the water is completely expelled from the tube into the aquarium
Velocity is calculated by programming the flow rate (i.e. .833ml/s)*distance fluid traveled (i.e. 0.0326m) = 0.026m/s² . Record the maximum velocity/frame

To insure accurate measurement of radius data to 20% and apply to all framesr, take 6 measurements from the same side of the torus half from the core to the outside wall and average them: radius 1
