WebDensity and surface tension are from the literature [9]. Sampling volumes were introduced to calculate the percentage of entrained air (i.e. percentage of gas porosity) as the ratio between entrained air volume and the total sampling volume. The entrained air vol- ume was evaluated after complete solidification of the simulated sample. WebPorosity is the percentage of void space in a rock. It is defined as the ratio of the volume of the voids or pore space divided by the total volume. It is written as either a decimal fraction between 0 and 1 or as a percentage. For most rocks, porosity varies from less than 1% to … Data: Porosity and density measurements. Porosities and densities of Wisconsin’s …
