Document Summary
Uses stokes law: just need to know why particles fall at different rates due to friction i. e . depends on how thick fluid is (water vs honey) Use a sieve and use that for grain size distribution. Different textures have different properties (see behaviour of soils chart. Well graded; lots of different sizes, well sorted means all the same size. Particle density: mass of solid material/ volume of solid material. 2. 65 gm/cm3 is density of quartz; starting point for all soils. Dry bulk density: mass over volume= mass/ volume of soil+air+water. Porosity= n= volume of voids over total volume= (air+water)/(soil+air+water) Mass water content= mass of water content/ mass of soil. Volumetric water content= volume of water/ volume of soil+ volume of voids. When asked for water content: asking for volumetric content. Degree of saturation: volume of water/ volume of air. Void ratio= e= volume air+ volume water/ volume soil.
