They are: Coarse-grained soils (CGS) which contain 50 percent or less of fines;; Fine-grained soils (FGS) which contain more than 50 percent fines;; Highly organic soils which are peat, muck, humus or swamp soil.; The coarse- and fine-grained soils are subdivided according to either the particle … WebThe formula of Stoke’s Law is presented below: where: D: The maximum diameter of soil particles corresponding to the percentages indicated by a single hydrometer test reading. μ: The fluid’s viscosity. v: the terminal velocity of settlement. γ s: The unit weight of soil particles. γ f: The unit weight of the fluid

WebOct 5, 2024 · Conventionally, we would say that the coarse fraction is 90% of the weight, and that the gravel portion of the coarse fraction is 11%/0.9 = 12.1%. Since the sand portion is 100% – 12.1% = 87.9%, the sand portion is greater, and thus the soil is a sand. WebPart 2 - Mechanical Analysis of Soil. Mechanical analysis is the determination of the size range of particles present in a soil, expressed as a percentage of the total dry weight.
