Webporosimeter. 1. n. [Formation Evaluation] An instrument for measuring the pore volume, and hence the porosity, of a core sample. The term is also used for some instruments that actually measure grain volume, such as the Boyle's Law Double-Cell method. Pore volume is then obtained from the difference between bulk volume and grain volume. WebJan 1, 1970 · The pore-size distributions of the compacted specimens were measured through the mercury intrusion porosimetry (MIP; ASTM 2010a [46]) using an autopore IV 9510 porosity instrument (American ...

WebPorosity measurement of the gas-bearing shales also has distinct characteristics. Organic-rich shales exhibit more variability, higher density porosity, and lower neutron porosity. … WebMercury porosimetry is used to measure the porosity of a material by applying controlled pressure to a sample immersed in mercury. External pressure is required for mercury to penetrate into the pores of a material due to high contact angle of mercury. The amount of pressure required to intrude into the pores is inversely proportional to the size of the pores. optim health patient portal

WebThe Paper Roughness & Porosity Tester measures surface roughness and air permeance according to industry standard methods. It makes it possible to meet this demand with accurate measurements to help control paper roughness. Achieving uniform ink coverage is essential to high-quality printing, and can only be achieved with a uniform paper surface. WebThe porosity of a sample is equal to the “areal porosity” provided that pore structure is random. The areal porosity is determined on polished thin sections of a sample. It is often necessary to impregnate the pore with some material such as wax, plastic, color, or wood’s metal in order to make pores more visible and/or distinguishing interconnected pore from … Webporosimeter. 1. n.
