WebMar 7, 2024 · Therefore the fluid streamlines always represent particle trajectories for particles perfectly coupled to the flow in steady-state. The particles feel all forces that the flow feels, as they ARE the flow. The main difference between a flow system and a uncoupled bunch of particles is pressure. – AtmosphericPrisonEscape. WebV = K * i. (where V is the velocity of the groundwater flow, K is the hydraulic conductivity, and i is the hydraulic gradient). We can apply this equation to the scenario in Figure 14.5. If we assume that the permeability is 0.00001 m/s we get: V = 0.00001 * 0.08 = 0.0000008 m/s. That is equivalent to 0.000048 m/min, 0.0029 m/hour or 0.069 m/day.
