WebbPorosity and Permeability Description: Students test the porosity and permeability of sand, gravel, and clay. Objectives: Students will understand that: All grades: • water is stored underground in the spaces (pores) between grains of sediment; and • the size of the grains of sediment affects how much water can be stored in the pore spaces. Webb31 juli 2015 · It was observed that during the tests and with the progression of compaction, permeability k decreases and non-Darcy factor β increases with decreasing porosity φ. The k-φ and β-φ plots show that as the sizes of disintegrated coal samples are getting smaller, there are more fluctuations between the porosity values with their corresponding values …
