Vortex Apparatus

The product consists of a transparent vessel on a support frame, which mounts on a DigitalHydraulic Bench. A low-voltage, variable-speed motor rotates the vessel aboutits vertical axis. The Vortex Apparatus enables students to produce both freeand forced vortices, and measure the vortex water surface profile. To produce a forced vortex, studentsadd water to the rotating vessel until it is about half full. A forced vortexforms. After a few minutes the vortex becomes constant, and students canmeasure the surface profile using the traverse probe. A speed-control unit (included), sited away from the mainapparatus, controls the speed of rotation. Students can also measure distribution of total head by replacing the traverseprobe with a Pitot tube. The traverse probe canmove both horizontally and vertically, and both axes have linear scales.
