A rotational viscometer contains a fluid that has an apparent viscosity of 10 cp at a rotor speed of 600 грт. a. Make a plot of fluid velocity vs. radius for radii between the bob radius r, and the rotor radius r2. Is the velocity profile approximately linear as in the case of the stationary and moving plates discussed in the previous section? b. Make a plot of shear rate y =r(dw/dr) vs. radius for radii between the bob radius and the rotor radius r2. Is shear rate approximately constant be- tween r, and r2? c. Make a plot of shear stress 7 vs. radius for radii between the bob radius r and the rotor radius r2.
