An investigation was conducted to study the influences of certain physical properties of the porous medium on the flow phenomena. An equation, representing hydraulic gradient as a function of bulk velocity, was developed by analyzing the Navier-Stokes equations. During the development of the equation it was shown that energy losses caused by turbulence being small could be neglected in comparison to the energy represented by convective terms. Two dimensionless parameters were developed from the flow equation, and a unique relationship was shown to exist between them for all porous media studied in this investigation. The characteristic length of the flow was shown to have linear relationships with particle diameter obtained from sieve analysis, and pore and grain diameter obtained from cut-section data of porous media.
