Question: Velocity profiles and the stress components ij. For each of the following velocity distributions, draw a meaningful sketch showing the flow pattern. Then find all

Velocity profiles and the stress components τij. For each of the following velocity distributions, draw a meaningful sketch showing the flow pattern. Then find all the components of 'r and pvv for the Newtonian fluid. The parameter b is a constant.

(a) vx = by, vy = 0, vz = 0

(b) vx = by, vy = bx, vz = 0

(d) vx = – ½bx, vy = – ½by, vz = bz
