Consider two-dimensional, steady, incompressible flow through the plane converging channel shown. The velocity on the horizontal centerline (x axis) is given by V =V1 1+ x L i. Find an expression for the acceleration of a particle moving along the centerline using

(a) the Eulerian approach and

(b) the Lagrangian approach. Evaluate the acceleration when the particle is at the beginning and at the end of the channel.
