WebThe porosity of a soil depends on several factors, including (1) packing density, (2) the breadth of the particle size distribution (polydisperse vs. monodisperse), (3) the shape of particles, and (4) cementing. Mathematically considering an idealized soil of packed uniform spheres, ϕ must fall between 0.26 and 0.48, depending on the packing. Spheres … WebAnswer: Porosity is fraction of open space to solid material, usually expressed as a percentage. Porosity ranges from zero to 100 percent.
