| Abstract | ||
| A study has been conducted to examine several selected water filter's media, namely, crushed silica, crushed anthracite coal, glass beads, crushed pocilinaite and crushed garnet. Large spread of particle size (0.5mm-2mm), porosity (35%-60%) and physical temperature (20oC-80oC) were tested in order to validate the experimental modeling of both Darcy’s and Forchheimer’s laws parameters. Typical constants of head loss in porous media as functions of velocity using Forchheimer,s model(L= aV+bV2) has been correlated by using hydraulic conductivity coefficients a*,b* which are experimentally evaluated at based conditions (Tw=25oC) ,(n=50%),(d=1mm).The basic conclusion of a wide ranges of experiments show those empirical equations for different selected porous media and filter's characteristics in the forms | ||
