Extracted text: 4–17 Consider steady, incompressible, two-dimensional flow through a converging duct (Fig. P4–17). A simple approximate velocity field for this flow is V = (u, v) (U, + bx)ỉ – byi | where U, is the horizontal speed at x = 0. Note that this equation ignores viscous effects along the walls but is a rea- sonable approximation throughout the majority of the flow field. Calculate the material acceleration for fluid particles passing through this duct. Give your answer in two ways: (1) as acceleration components a, and a, and (2) as accelera- tion vector a. y Uo
