The present paper deals with some examinations on the kneading effect of thermoplastics by the screw extruder from a hydrodynamical standpoint view. Provided that the ratio between the rate of flow and drag flow K=Q/Qd is known, the rate of shear D, its mean D^- and the shear amount per unit length γcm, its mean γcm^^- in the direction of the channel depth can be determined. Consequently if the distribution of K along the screw length is known, we can guess the total amount of kneading.
