Falling head permeability apparatus

DESCRIZIONE GENERALE
DESCRIZIONE GENERALE
The soil permeability is a very important factor to study the behavior of soil in its natural condition with respect to water flow. The falling head method is particularly suitable for fine-grained soils such as clay-like or silty soils in the range of 1x10-2 to 1x10-6 cm/s. For relatively coarse grained soils such as sands and gravel see Constant Head permeability apparatus.
The test is performed with a permeability cell (38-T0185/1), which has to be connected to a manometer stand (38-T0185/2). During the test the cell is placed in a soaking tank (38-T0185/3) fit with overflow tube and the saturation is verified with the Vacuum control panel (38-T0185/4). As an option the apparatus can be completed with a suitable de-airing tank (28-WF4220/A) and De-airing system. See accessories.
The permeability cell is made of plated steel. The base and the top are clamped with stainless steel rods. Complete with 75 micron gauze. Supplied complete with 2 m tubing.
