This module enables to study the characteristics of flow in an open channel. The channel is fed with the water coming from the hydraulics bench via a stilling tank that reduces the turbulence of the liquid. The channel made of transparent acrylic material is high and narrow and incorporates weirs of adjustable height at the inlet and at the outlet in order to control the liquid level inside. This equipment is also equipped with a dye injection system that allows a better visualization of the flow on the different hydrodynamic models available in the central part of the channel. The water coming from the flow channel is discharged into the hydraulics bench and it returns to the supply tank of this bench for being recycled.
