Some experimental data for shearing stress τ and shear strain rate γ obtained for a particular non-Newtonian fluid at 80?F are shown below. Please plot these data and fit a second-order polynomial to the data using graphing software. Estimate the apparent viscosity of this fluid when the shear strain rate is 70 s-1, and compare this value with the viscosity of water at the same temperature.
