Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume...

Porosity sealing is done through the process of vacuum impregnation. Vacuum impregnation is a preferred OEM process that seals porosity and leak paths...

Effective porosity is most commonly considered to represent the porosity of a rock or sediment available to contribute to fluid flow through the rock or...

must be eliminated. They are broken down into five main categories: gas porosity, shrinkage defects, mould material defects, pouring metal defects, and...

Gas porosity is the fraction of a rock or sediment filled with a gas. Determining the true porosity of a gas filled formation has always been a problem...

of varying sizes as well as organic compounds. In order to understand porosity better a series of equations have not been used to express the quantitative...

Porosity Storage Reservoirs are man-made water storage reservoirs located in shallow alluvial (sand and gravel) deposits. The porosity, or void space,...

field of formation evaluation, porosity is one of the key measurements to quantify oil and gas reserves. Neutron porosity measurement employs a neutron...

Hydrogen gas porosity is an aluminium casting defect in the form of a porosity or void in an aluminium casting caused by a high level of hydrogen gas...

There are low, medium and high hair porosity. Low hair porosity is when the hair cuticles are tightly shut. Low porosity hair has difficulty obtaining moisture...
