Evaluation of Different Methods for Determining the Entrance Pressure Drop in Capillary Rheometry
Applied Rheology, 2008 Two approaches for determining the entrance pressure drop in capillary rheometry were compared with low-density polyethylene and polystyrene melts as test fluids. Direct measurements with the orifice die were found to yield higher values for the entrance
