Permeability Apparatus

Permeability Apparatus (Falling Head Permeability) The apparatus is used for the laboratory determination of permeability of soil using a constant or a variable head. This test is recommended for soils with co-effcient permeability in the range of 0 10-3 to 10-7 cm/sec. The maximum particle size of the soil which can be tested in the mould is 10mm. The equipment comprises one each : Gun metal mould, 100mm I.D. x 127.3mm high x 1000ml Volume. Gun metal mould extension collar, 100mm dia x 60mm high for the above mould. Gun metal drainage base plate with a recess for a porous stone.
