An idealized incompressible flow has the proposed three-dimensional velocity distribution V = 2xyi + f(y)j zyk (a) Find the appropriate form of the function f(y) that satisfies the continuity relation. Show all of your work. (b) If f(y=0) = 0, find the acceleration field. (c) Is the flow rotational? Is so, what is the angular rotation? (d) Are particles in the flow subject to deformation? If so, how?
