POROSITY of POWDERS authorSTREAM

Nov 10, 2013  PowerPoint Presentation: A mercury porosimeter is an instrument that allows the total volume of a powder to be determined, as well as the volume of pores of different sizes: A known mass of powder is submerged in mercury. At ambient pressure, the mercury does not invade the interparticle spaces or the pores of the sample.

Porosity - SlideShare

Porosity • Porosity is a measure of the void space in rock, hence, measures how much HC in rock • Porosity φ = Vp/Vb = (Vb-Vm)/Vb; Vb = Vp + Vm – theoretically, φ varies from 0% - 47.6% – In practice, φ varies between 3% and 37% • Porosity is a function of particle size distribution: – Framework materials (sandstone) – high φ ...
