Viscosity data for ABS are shown in the plot below, where thetemperatures of the viscosity data are given in K$.$ At a shear rate of $100$s $^-1$ theviscosity of ABS at $473$ K is $4920$ Pas, and at a shear rate of $10000$s $^-1$ the viscosity is$310$ Pas at the same temperature. The power$-$law fit to the viscosity data at $473$ K isthe dashed line shown in the figure, which intersects a vertical line drawn for y $=1$ata viscosity value of $78,000$ Pas. Use this information to determine the power$-$lawmodel parameters m and n for ABS at $473.$
