FME24 丘里管的多孔床（达西方程）的研究

The Unit for the Study of Porous Beds in Venturi Tubes (Darcy´s Equation), "FME24", designed by EDIBON, for the study of porous beds in Venturi tubes (Darcy's Equation), allowing the complete and detailed understanding of this equation.

The unit is formed by a circular section conduit with a truncated cone shape, transparent, and with pressure taps that allow measuring simultaneously the values of static pressure corresponding to any point of

different sections.

It also has three another conduits, full of sand of different diameters of grain.

The conduit ends can be extracted, so they can be placed in a convergent or in a divergent way in regard to the flow direction.

There is a probe (Pitot’s tube) that moves along the section in order to measure the height of each section (dynamic pressure).

The flow velocity in the unit can be modified by adjusting the control valve and by using the Hydraulics Bench (FME00) or Basic Hydraulic Feed System (FME00/B).
