Porosity of sand vs clay
WebPorosity Porosity φ is the fraction of the total soil volume that is taken up by the pore space. Thus it is a single-value quantification of the amount of space available to fluid within a specific body of soil. Being simply a fraction of total volume, φ can range between 0 and 1, typically falling between 0.3 and 0.7 for soils. Web- Sand: soil particle between .05 and 2.0 mm in diameter - Silt: soil particle between .002 and .05 mm in diameter - Clay: soil particle less than .002 mm in diameter Sand is the largest mineral particle and it has more pore space between its particles than silt or clay. Silt particles are smaller than sand, but larger than clay particles.

WebDefinition. Soil Porosity is the amount or percentage of pore space in a volume of soil. The amount of porosity in a soil depends on the minerals that make up the soil and the amount of sorting that occurs within the s oil structure. For example, a sandy soil will have larger porosity than silty sand, because the silt will fill in the gaps ... WebThese ranges indicate a huge difference in size between a sand-size particle and a clay-size particle. For example, ... Numbers in the range of 25 to 50% are common, and the porosity is always between 0 and 100%. The void ratio e is the ratio of the volume of voids Vv over the volume of solids Vs.
