Fluids for which the shearing stress, , is not linearlyrelated to the rate of shearing
Chapter 1, Problem 1.63(choose chapter or problem)
Fluids for which the shearing stress, , is not linearlyrelated to the rate of shearing strain, , are designated as nonNewtonianfluids. Such fluids are commonplace and can exhibitunusual behavior, as shown in Video V1.6. Some experimentaldata obtained for a particular non-Newtonian fluid at 80 F areshown below.Plot these data and fit a second-order polynomial to the datausing a suitable graphing program. What is the apparent viscosityof this fluid when the rate of shearing strain is 70 s1? Is thisapparent viscosity larger or smaller than that for water at the sametemperature?
