Digital Corollis Component of Acceleration Apparatus
Product Code : EL-DOMLE-10771
Quick Answer:
The Digital Corollis Component of Acceleration Apparatus demonstrates how the Coriolis force – the apparent or inertial force that deflects a mass moving within a rotating reference system – affects motion, a phenomenon relevant to meteorology, oceanography and engineering systems such as cranes, gearboxes and robots. A submersible pump on a rotatable arm produces a radial water jet inside a transparent, scaled water tank; as the arm’s electronically controlled, digitally displayed speed and direction change, students can visibly observe and measure the Coriolis deflection of the jet against the tank’s scale.
When a mass moves relative to the reference system within a rotating reference system, this movement is deflected; this deflection is caused by the Coriolis force, an apparent or inertial force. The Coriolis force plays a crucial role in meteorology and physical oceanography, since it influences the course of air and water currents due to the Earth’s rotation, and in engineering it occurs whenever a rotational motion interferes with a further movement of the same object, as can happen in cranes, gearboxes or robots. The experimental unit is designed to clearly demonstrate the effect of the Coriolis force in a rotating reference system: a transparent water tank with a submersible pump is placed on a rotatable arm and then rotated, and within this rotating reference system the pump produces a water jet in a radial direction. Depending on the flow rate of the pump or the water velocity, as well as the speed and direction of rotation, the water jet is visibly deflected due to the Coriolis force, and the degree of deflection can be determined by means of a scale on the water tank; the rotation speed itself is continuously adjustable, electronically controlled and digitally displayed.
