Abstract
Mathematical expressions of velocities,shear stresses for Newtonian laminar field near the pins in pin barrel extruder and machine's power are presented. The computed power exhausted by the pins is verified by experiment. It is found for the experimental nature rubber-carbon black compound that there is excellent agreement between computed and experimental values.
