Problem 5.1 Table 5.6 gives the experimental data obtained for an HDPE (melt density of 0.745gm/cm3 ) at 200C using a continuous-flow capillary rheometer for three different LD ratios. Table 5.6 Experimental data for Problem 5.1 aD=0.3175cm. (a) Construct the Bagley plot for the HDPE. (b) Construct the flow curve for the HDPE after making the Bagley end corrections. \begin{tabular}{|r|r|r|} \hline L/D & \multicolumn{1}{|c|}{(Mpa)} & \multicolumn{1}{|c|}{} \\ \hline 4 & 2,556 & 93,5 \\ \hline 4 & 3,169 & 189,2 \\ \hline 4 & 4,065 & 357,7 \\ \hline 4 & 4,681 & 497,2 \\ \hline 8 & 3,655 & 82,7 \\ \hline 8 & 4,333 & 148,2 \\ \hline 8 & 6,22 & 359,3 \\ \hline 8 & 6,769 & 457,1 \\ \hline 12 & 5,153 & 93 \\ \hline 12 & 6,651 & 181,8 \\ \hline 12 & 8,389 & 361,4 \\ \hline 12 & 8,897 & 423,4 \\ \hline 16 & 6,726 & 84,9 \\ \hline 16 & 8,569 & 182,6 \\ \hline 16 & 10,591 & 356,2 \\ \hline \end{tabular}
