Permeability: Permeability is the ability of fluids to pass through a process material. It is measured in millidancy (MD) or Darcies (D) and expressed by k. According to Darcy’s law, Where, Q = Rate of fww K= Permeability (p1-p2) = Pressure drop across the sample A =...

Sphericity measures how closely a particle’s shape resembles a sphere. It helps in understanding grain durability, transport history, and geological processes. A perfect sphere has a sphericity of 1.00, while other shapes have lower values. This concept is crucial in...
