WebApr 8, 2024 · The porosity results obtained from the ratio of the volume of the pores detected by XCT to the total volume of the test sample. Figure 7a summarizes the relationship between VED, porosity, and relative density. The minimum porosity is 0.53%, in other words, the maximum relative density of the forming block is 99.47%.

WebApr 11, 2024 · The porosity and particle diameter mainly affect the heat transfer coefficient (HTC). At a low heat flux, the sintered wick with low porosity and a small particle diameter has a higher HTC. The HTC of porous wicks, with a larger particle diameter and porosity, decreases slower. The optimal porosity ranges from 46.4 ± 2.5% to 51.8 ± 2.5%. WebThe best way to calculate total porosity is using the density log, correcting for lithology (using grain density) and fluid density (using invaded zone resistivity or neutron logs). For completeness the formula recommended is: phiT = (RHOma - RHOB)/ (RHOma - (RHOMF.SWXO+RHOHC. (1-SWXO))) tax calculator for payroll

WebJan 18, 2024 · The method of estimating porosity from the density requires determining the matrix density (ρ ma ), the density log reading (ρ b ), and the fluid density (ρ fl at the depth of interest. The matrix density is determined by the lithology. Normally, sandstone is 2.65 g/cm 3, limestone is 2.71 g/cm 3, and dolomite is 2.87 g/cm 3.
