1B.1 Velocity profiles and the stress components T.. For each of the following velocity distributions, draw a meaningful sketch showing the flow pattern. Then find all the components of T and pvv for the Newtonian fluid. The parameter b is a constant. (a) v, by, vy = 0, v = 0 = (b) v.=by, vy = bx, v = 0 (c) v = -by, v = bx, v = 0 vy (d) v = bx, v = -by, v = bz v, 1B.2 A fluid in a state of rigid rotation. (a) Verify that the velocity distribution (c) in Problem 1B.1 describes a fluid in a state of pure rotation; that is, the fluid
