The HB100A Free and Forced Vortices unit enables students to easily investigate the concept of vortices. The apparatus allows a clear 360° view of the experiment, along with no visual refractory interference thanks to its single skin clear plastic tank. A pure forced vortex is produced by spinning the tank via an internal motor controlled by a “smart” front mounted speed controller which responds to accidental interference of the spinning tank to ensure student safety. Interchangeable free vortex orifices allow investigation of different sized free vortices. Measurement of the different profiles is achieved with a digital sliding horizontal scale and a precision engraved needle point rod allowing an infinite degree of measurement points to be achieved. The apparatus operates from the atop the HB100 Hydraulics bench base unit.
