Practice Water in an aquifer moves with a flux of 30cm/day. The average soil particle size is 1.5 mm. Find the Reynolds number and check whether Darcy's law is applicable (water density is 1000kg/m³ and water viscosity is 1.137x10-3 Ns/m2). Solution Convert all the units to metre, Newton and second 1000 x(0.3/24/3600)x 0.0015 Re = = 0.0046 1.137 x10-3 Since Re < 1, Darcy's law is applicable.
