WebJan 18, 2024 · Neutron and density logs each react to both lithology and porosity, so by analyzing the two logs together, one can begin to distinguish lithology from porosity. … WebA second method, the Resaturation Method, uses a clean dry core sample and resaturates it with a fluid of known density.The change in weight of the sample can then be used to determine the pore volume, V p, of the sample. Since the fluid can only enter or leave the connected pores, the porosity obtained from the resaturation method is the effective …

WebJan 25, 2024 · Where the porosity of a feed material is a significant concern, it can be studied using the mercury porosimetry technique. Various AM feeds, including most metal powders in the sub-45-micron size range, have low porosity, which means that gas pycnometry tends to return true density values. Envelope Density WebCalculate the porosity of a soil sample that has a bulk density of 1.35 g/cm3. Assume the particle density is 2.65 g/cm3. Porosity = (1-(rb/rd) x 100 = (1-(1.35/2.65)) x 100 = 49% 7. Calculate the porosity (n) of a 250 cm3 clod that contains 140 cm3 water when saturated. Porosity = Vair+ Vwater/Vtotal= 140cm3/250cm3= 56% 8.
