The equipment has been designed to study the characteristics of free and forced vortices inside a cylinder of acrylic material. The free vortex is generated by water discharging through an interchangeable orifice available at the base of the cylinder and the resulting profile is measured with a series of graduated rods placed at a known distance from the centre of the tank. The forced vortex is induced by a blade at the base of the cylinder which is rotated by two jets of water. The speed at any point in the free or forced vortices may be measured with 3 Pitot tubes placed at different distances from the centre.
