The following measurements were made in a Couette viscometer with a cup radius of 26mm, a bob radius of 24mm, and a bob length of 35mm. (a) Use these data to determine the values of the shear stress, shear rate, and apparent viscosity of the sample. (b) Determine an appropriate rheological equation and the rheological parameters that describe this fluid. [Taken from the 2011 Test No. I]
