$($a$)$ Classify each fluid $($A$,$ B$,$ and C in the plot$)$ as Newtonian, shear thickening, and$/$or shear thinning

according to the plot below. $[9$ pts$]$

Shear Rate

Fluid A $-$

Fluid B $-$

Fluid C $-$

$($b$)$ The Ford Cup viscometer is used to measure the viscosity of fluids A$,$ B and C in $($a$).$ The Ford

Cup is filled with fluid and the time for the fluid to flow through the orifice at the bottom of the

cup is measured. Which fluid will have the longest flow time according to the figure above? $[6$ pts$]$

$($c$)$ For the fluid A in $($a$),$ the viscosity do NOT vary with the temperature. Is the statement true or

false? $[5$ pts$]$

True $/$ False
