Determination of Pressure Drop of Plastic Lubricant Flow in Pipe

Abstract

The paper deals with determination of pressure drop depending on mean velocity at flow of ecological plastic lubricant type MOGUL EKO L1 in steel pipe. Pressure drops are experimentally determined at pulsating lubricant flow for two different inner pipe diameters. The pressure drop is subsequently calculated for steady flow of the mentioned lubricant by application of Bingham rheological model. The calculated values are subsequently compared with the experiment.
