$3\mathrm{.}14$ When a Casson fluid is tested in a viscometer, the data shown in Table $3\mathrm{.}9$ are obtained. What flow rate do you expect if a pressure drop of forces this same fluid through a tubelong with radius? Assume laminar flow. You may find that making a graph is useful as an intermediate step; before getting out your calculator, think carefully about what you want to plot.
