CONSTANT HEAD PERMEABILITY APPARATUS
The Constant Head Permeability apparatus is used for testing the permeability of granular soils (sand and gravels).
The specimen is formed in a permeability cell and water is passed through it from a constant level tank. Take off point located along the sides of the permeability cell are connected to three manometer tubes mounted on a panel complete with a meter scale.
Water passing through the specimen is collected and measured, either for a specific quality or over a period of time. The reduction of head is noted from the variation of water level in the manometer tubes.
Constant Head Permeability Set, consists of a 80 mm dia. constant head permeability cell, wooden stand with 3 pcs. manometer tubes, constant level tank, and 3m connection hoses. (Water De-Airing equipment and tamping rod should be ordered separately.)
Constant Head Permeability Set, consists of a 120 mm dia. constant head permeability cell, wooden stand with 3 pcs. manometer tubes, constant level tank, and 3m connection hoses. (Water De-Airing equipment and tamping rod should be ordered separately.)
