a) Find v,v, and v for the following flow fields: vx=yvy=0vz=0vx=yvy=xvz=0vx=(/2)xvy=(/2)yvz=zvx=xvy=yvz=z where the parameters ,,, and are constants with position and have dimension T1. [20 Points] b) Do the velocity fields given in a) satisfy the equation of continuity for incompressible flow? Are they rotational or irrotational flow? [5 Points]
