pórusosság
Pórusosság refers to the measure of void spaces in a material. These voids, or pores, can be filled with a fluid, such as water, oil, or gas, or they can be empty. The volume of these pores relative to the total volume of the material is known as porosity, often expressed as a percentage. Different materials exhibit varying degrees of porosity. For instance, rocks like sandstone and limestone are porous, allowing them to store significant amounts of groundwater. Conversely, materials like granite or basalt are generally considered non-porous.
Porosity plays a crucial role in various scientific and engineering disciplines. In geology and hydrogeology, it
