Effect of the Intensive Plasticizing Zone Design on the Effectiveness of Corotating Twin-Screw Extrusion

Table 2

Analysis of variance results of the model of screw drive torque M, where the coefficient of determination is R²=0.93 and its corrected value is =0.91. SS: sum of squares, df: number of the degrees of freedom, MS: mean sum of squares, F: values of the test statistic, p: value of probability corresponding to the test statistic value.
