## Description Générale

The Coriolis Force Demonstration Unit, "MDFC", is used to observe the deflection of a jet of water generated by a pump attached to a rotating arm that rotates to different speeds in a horizontal plane. An electronically controlled motor rotates the arm at different speeds.

The pump is immersed in a transparent water tank and projects a jet of water in the tank. This jet is directed towards the center of rotation of the rotating arm in a closed circuit.

Depending on the speed and direction of rotation, as well as the water flow rate of the pump, the jet of water is deflected under the Coriolis Effect (force). The amount of deflection can be seen in the water tank and be determined by means of a scale on the water tank.

The pump is counterbalanced to ensure a smooth and stable running at high speeds.

The unit includes a electronic console with a speed controller for the motor and a digital display to show the different speeds of the motor, a flow rate controller for the pump and a digital display for the speed of the jet of water.

The unit is protected by a safety cover that disconnects it automatically when the lid is opened.

Optionally EDIBON recommends the Action Camera element, C-ACAM, to visualize and/or record the deviation of the water jet.
