eng	Flow of purely viscous fluids through filter screens	In this contribution, the dependence of the pressure drop on the volume flow rate was measured in the flow of purely viscous power law aqueous solutions of different polymers. Experiments were carried out with six filter screens differing in wire diameter, aperture dimension, and type of weaving. The pressure drop measurements were performed in a device consisting of a plastic pressure drop measuring cell of fifty mm in inner diameter with a calming tube of forty mm in length. It has been verified that the pressure drop can be expressed in the form of dependence of drag coefficient on power law Reynolds number.	purely viscous fluids;filtration screens;pressure drop;drag coefficient
