FLOW THROUGH ORIFICES
The system has been designed to study the contraction phenomenon that occurs when a fluid pass through an orifice.
It has three nozzles whose geometry differs from each other in order to perform tests at different conditions. It is provided with a Pitot tube through which it is possible to measure the fluid speed at the outlet.
To perform the tests successfully, the system has a jet diameter measuring device that can be regulated for more accurate measurements.
Moreover, it is provided with a water column gauge which allows the water level measurement in the tank and the height of the water jet.
