Grain density formula

WebCalculate the density of the sand. Remember that density is the mass per unit volume. Divide the mass of the sand by the volume of the sand. Calculate the air space volume. It will be equal to the volume of the sand alone plus the volume of the water alone minus the volume of the sand/water mixture. Calculate the fractional air space. WebFor example the density of quartz is 2.65 g cm-3, and a clean sandstone should have a mean grain density close to this value. 5.2 Controls on Porosity The initial (pre-diagenesis) porosity is affected by three major microstructural parameters. These are grain size, grain packing, particle shape, and the distribution of grain sizes.
