7) In a pseudoplastic liquid, blending times at Re ＜ 1,000 are much longer than in newtonian liquids under the same impeller conditions.(A)O(B)X

8) In the free mot otion of nonspherical particles through a fluid, the orientation is constantly changing. Thus, the effective drag on the particle is less than for the motion of the fluid past a fixed particle.(A)O(B)X
