Soil Hydrometer Testing, Easy Guide for Hydrometer Analysis

WebThe hydrometer method requires the use of sodium hexametaphosphate, which acts as a dispersing agent to separate soil aggregates. The soil is mixed with the sodium hexametaphosphate solution on an orbital shaker overnight. The solution is transferred to one liter graduated cylinders and filled with water. WebParticle Size Analysis II – Hydrometer Analysis GEL 324 Sedimentology Introduction Hydrometer analysis provides an approximate particle-size distribution for particles whose median diameters smaller than 4φ (0.0625mm), which includes silt and clay size particles. The procedure utilizes Stoke’s Law of settling velocity for goodwood 79th members meeting
