The Fluid flow through woven screens in a circular pipe was measured to determine the resistance of those woven screens under the steady state. The screens included in this study are eighteen screen made of round wire forming a square mesh. Results show that after passing through all plain square screens, the velocity profiles represent three different patterns based on the coefficient of porosity β. The relationship between the resistance coefficient K and the wire diameter Reynolds number can be classified into three classes according to the three different patterns of the velocity profile. The use of the average velocity U/β and pore spacing l as a characteristic velocity and scale makes a more general correlation between the resistance coefficient and the Reynolds number. The relation between K and β depends on the wire diameter Reynolds Number.
