← ScienceWhich outcome signifies flow regime transition according Reynolds number increase within porous media?
A)Darcy's law loses predictive power✓
B)Capillary forces dominate fluid motion
C)Molecular diffusion overwhelms convection
D)Surface tension minimizes interfacial area
💡 Explanation
Laminar to turbulent transition invalidates Darcy's law, because inertial forces become significant; therefore Darcy's predictive capability diminishes, rather than capillary forces dominating or diffusion/surface tension increasing, which are relevant and dominate at lower Reynolds numbers instead.
