This equipment is designed to produce and measure free and forced vortices. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied) for a water supply and flow measurement.

The equipment consists of a clear acrylic cylinder on a plinth. The free vortex is generated by water discharging through an interchangeable orifice at the base of the cylinder and the resulting profile is measured by a combined caliper and depth scale. The forced vortex is generated by a paddle at the base of the cylinder which is rotated by jets of water, and the profile is measured by a series of depth gauges. The velocity at any point in the free and forced vortices may be measured using a pitot tube.

Instruction manual is also included.
