Darcy's law is valid for only

WebFor Darcy’s law to be valid, the Reynolds number should be ________ a) greater than one b) less than one c) equal to one d) greater than five View Answer Answer: b Explanation: … Darcy's law is an equation that describes the flow of a fluid through a porous medium. The law was formulated by Henry Darcy based on results of experiments on the flow of water through beds of sand, forming the basis of hydrogeology, a branch of earth sciences. It is analogous to Ohm's law in electrostatics, linearly relating the volume flow rate of the fluid to the hydraulic head difference (which is often just proportional to the pressure difference) via the hydraulic conductivity.
