Four circumferential jets have been positioned along the cylinder's circumference, close to the bottom, of the circular, transparent tank that serves as the experimental setup. These jets aid in the development of free vortices. These jets are thought to provide very little torque. In order to study a smaller diameter, the orifice is reducing the bush. A variable speed motor can also be used to rotate the plate, forcing a forced vortex to emerge while the cylinder rotates around its vertical axis with the aid of a V belt. The depth of flow at any given site was seen to remain constant over time when the conditions reached a steady state. Measuring the resulting free surface, which indicates the variation of the total of the pressure and datum head, is a step in the experimental process.

• To plot the surface profile of a free and forced vortex by measurement of the surface profile coordinates and to show that total energy is constant throughout vortex.
