- •
Five homogeneous sand columns in diameter 1.075, 1.475, 1.85, 2.5 and 3.17 mm.
- •
Pre-Darcy flow and post Darcy flow were identified but no obvious linear flow.
- •
Reynolds number of two flow regimes increased as the particle diameter increased.
- •
New Reynolds number was defined to estimate the validation of Darcy’s law.
