With the help of a flow curve, describe what a shear thinning and shear thickening liquid mean.

The apparent viscosity of a non$-$Newtonian liquid at a given shear rate is the value indicated by a viscometer operating on the liquid at that shear rate. It is the viscosity that would be indicated by the viscometer if the liquid were Newtonian.

$($a$)$ Calculate the apparent viscosity of a $4$ wt$\%$ suspension of paper pulp in water $($whose power law parameters are n $=0\mathrm{.}575$ and K $=20\mathrm{.}02$ x $103)$at shear rates of $10$ S$-1$ and $1,000$ S$-1$

$($b$)$ Repeat for a $25$ wt$\%$ suspension of clay in water $($whose power law parameters are n $=0\mathrm{.}185$ and K $=1\mathrm{.}59$ x $103$
