TO-131-BS - Laboratory Permeability Apparatus (Falling Head)
Plated steel chamber head assembly.
Corrosion-resistant cast aluminum base assembly.
Includes accessories for conducting both constant and falling head permeability studies
Permeability is a property of soil that permits flow of water through its interconnecting voids. Permeability is an important engineering property that governs the rate of settlement of saturated compressible soil layers and the rate of flow of aquifer. Permeability is taken into account for pumping ground water, spacing well points for de-watering foundation sites for excavation, retention of water in reservoirs, design of dams and
selection of soils to be used for various zones of embankments of dams and reservoirs.
Falling Head Permeameters are used for testing remolded or undisturbed fine grained soil having less than 10cm/sec coefficient of permeability and Constant Head Permeameters are used for coarse grained cohesion less soils.
