The constant head permeability test experiment was chosen instead of the falling head test as the soil sample tested was coarse grained soil. In the experiment, Soil Mechanics Laboratory Manual. Equipment. 1. 2. Constant head permeameter. Graduated cylinder (250 cc or 500 cc). 3. Balance, sensitive up to O.lg. This test is an easy, cost effective way to determine permeability in a laboratory setting. Equipment Used. Figure 1. Constant Head Permeameter. Other EquipmentPurpose: The purpose of this test is to determine the permeability (hydraulic conductivity) of a sandy soil by the constant head test method. There are. Experimental procedure: 1- compact soil into constant head and place specimen over the bottom aggregates 2- place a filter and aggregates on top of the soil IS-2720 (Part-17):1986 (Reaffirmed-2016) “Methods of test for soils: Laboratory determination of permeability". 4. Procedure. 4.1 Constant Head Permeability Constant head permeability test is suitable for Cohesionless (Coarse and medium Sands) soils. PRESENTATION OF DATA: The coefficient of permeability is reported
