Falling Head Permeability Apparatus

Falling Head Permeability Apparatus

The apparatus is used for the laboratory determination of permeability of soil using a constant or a variable head.  
The maximum particle size of the soil which can be tested in the mould is 10mm.
This test is recommended for soils with co-effcient permeability in the range of 0-10-3 to 10-7 cm/sec.
