To visualize laminar and turbulent flow, the Osborne Reynolds experiment is used. The transition from laminar to turbulent flow can be observed above a limiting velocity. In the SB-VP-50 unit, the streamlines at different flows are represented in color using ink as a contrast medium. The experimental unit consists of a transparent pipe section with streamlined inlet and a honeycomb rectifier. The pipe section contains a horizontal, straight pipe and a 90° pipe bend. At the end of the experiment, the working medium water is returned to the base module. Alternatively, the water can be collected separately to avoid turbidity during the experiment. A heater for heating the water is controlled via the base module and causes a change in viscosity. In the experiment, ink is introduced into the flowing water as a contrast medium. Formation of the flow can be clearly observed. As the flow velocity increases, the first vortices are formed. These vortices increase with increasing flow velocity un
