Make a plot of shear stress (ordinate) vs. shear rate (abscissa) on Cartesian paper. Make a plot of shear stress (ordinate) vs. shear rate (abscissa) on log-log paper. b. Can the fluid behavior be accurately modeled by the Newtonian, Bingham plastic, or power-law model? e. Compute the apparent viscosity for each shear rate. Answer: 55 cp at 20 seconds -1. d. Compute the yield point and plastic viscosity using data taken at shear rates of 20 and 60 seconds. Answer: Ty 3.3 dynes/cm2; p=39 . e. Compute the consistency index and flow- behavior index using data taken at shear rates of 20 and 60 seconds -1. Answer: n=0.8; K=100 eq cp.
