The objective of this paper is to study effect of multi size media on behavior of fluid at post-Darcy flow regime as porous medias differences in the sizes and weight. Crude oil used as fluid within three types of medias (gravels, glass balls, SiLibeads), and Kozeny -Carman model is used to estimate the head loss experimentally under changing on the flow rate. There are two coefficients have effect on non-Darcy flow regime (Reynolds number, Forchheimer number) at the same time depends it's on

The permeability, porosity and Tortuosity are determined theoretically and all of them depend on properties of fluid and media. the test result shows the theoretical analysis from the Forchheimer number is directly proportional with effect of post-Darcy flow regime, and that non-Darcy behavior has good value with glass media (0.5166 porosity) .Porous media properties shows the permeability and non-Darcy coefficient have effect on non-Darcy behavior and inertia coefficient depends on porosity and properties of permeable bed.
