General Description
The Orifice and Free Jet Flow unit, "FME17", designed by EDIBON, allows the study of the different discharge and velocity coefficients in permanent or variable regime as well as the calculation of the discharge times.
The unit consists of a cylindrical methacrylate tank that enables to maintain a constant level and that is fed by the Hydraulics Bench (FME00) or by the Basic Hydraulic Feed System (FME00/B).
Two nozzles with orifices of different diameters are provided. They are placed in the base of the tank, and can easily be interchanged.
The trajectory of the jet can be drawn by following the position of some vertical needles placed in the annexed panel. These are adjusted by means of some command screws.
This panel includes a silk-screen scale that enables to measure the profile of the jet.
Adjustable feet permit levelling.
