Resumen
Equipment for regulation and visualization of transition between laminar and turbulent regimes of a fluid. An experimental didactic system is proposed for the regulation and visualization of the transition between laminar and turbulent regimes in liquid flows in circular section ducts. It consists of a tank or tank (1) containing a liquid (2) that is evacuated through a discharge pipe (5) that has a nozzle (6) at its entrance and a discharge valve (7) to the departure. The level of the liquid in the tank is regulated by a valve (3) and a level sensor (4). In front of the nozzle a flow of dye (10) is injected through a needle (13) which flows from a reservoir (11) regulated with a valve (12). The evicted liquid, together with the dye, is measured by a flow meter (8) and collected in a discharge tank (9). It has several accessories for control and automation of the experiment.
