An experimental investigation on the effect of converging boundaries on flow through porous media was carried out in a converging permeameter using crushed rock of size 4.73 mm as the media and water as fluid. The influence of converging boundaries on the resistance law relating the friction factor (f_R) the and Reynolds number (R_R) using the hydraulic radius as the characteristic length is examined. The present study aims to develop theoretical curves similar to the Moody diagram used in pipes, and to study the variation of f_R and R_R for different C_R values taken as the third parameter for different ratios of the radii and for different radial lines. The relationships existing between the linear parameter a, the nonlinear parameter b, and the hydraulic radius R are also obtained theoretically and are verified with the experimental data.
