The viscosity of blood is to be determined by measurements of shear stress, $,$ and rate of

shearing strain, $d\frac{u}{d}y,$ obtained from a small blood sample tested in a suitable viscometer. The

following data are obtained:

a$.$ At a shear strain rate of $11\mathrm{.}25s^{-1},$ what is the viscosity of the blood sample in units of

$cP?$

b$.$ Using the data above, plot the shear stress as a function of rate of shearing strain using

graphical software $($such as Excel, Mathematica, etc$)$ using log$-$log axes. Label all axes,

including units, for full credit.

c$.$ Is this fluid Newtonian, shear thickening, or shear thinning? Explain your reasoning.

$($Hint: you might choose to include a plot to support your answer.$)$
