3. A viscometric flow of a biofluid in the narrow gap between large parallel plates is shown. The velocity field in the narrow gap is given by V=U(y/h)i^, where U=4mm/s and h=4mm. At t=0 two lines, ac and bd, are marked in the fluid as shown. Evaluate the positions of the marked points at t=1.5s and sketch for comparison. Calculate the rate of angular deformation and the rate of rotation of a fluid particle in this velocity field
