Porosity (Paperback)

High Quality Content by WIKIPEDIA articles High Quality Content by WIKIPEDIA articles Porosity is a measure of the void spaces in a material, and is a fraction of the volume of voids over the total volume, between 0-1, or as a percentage between 0-100%. The term is used in multiple fields including pharmaceutics, ceramics, metallurgy, materials, manufacturing, earth sciences and construction. Porosity is a fraction between 0 and 1, typically ranging from less than 0.01 for solid granite to more than 0.5 for peat and clay, although it may also be represented in percent terms by multiplying the fraction by 100. The porosity of a rock, or sedimentary layer, is an important consideration when attempting to evaluate the potential volume of water or hydrocarbons it may contain. Sedimentary porosity are a complex function of many factors, including but not limited to: rate of burial, depth of burial, the nature of the connote fluids, the nature of overlying sediments (which may impede fluid expulsion).
