In-Plane Permeability Test Apparatus

This test is necessary for drainage application. The permeameters can be of parallel flow or radial flow type. In either case, flow occurs along the plane of the permeamatre. In the apparatus, flow occurs radically outwards, from a central hole to the periphery of a circular specimen. The transmissivity is defined as the volumetric rate of flow per unit width of geotextile and unit hydraulic head. Essential Accessories Overhead Tank Loading unit, 300 kPa capacity
