Flow of a liquid of constant density () occurs through a 180-degrees bend as shown in Fig. 9 (see next page). The pipe area (A) and velocity (U) at the inlet and outlet are the same. Assuming the velocity through the pipe is uniform across all cross-sections, find: (a) Vn^ at the inlet and the outlet; and (b) momentum flux (i.e., CSV(Vn^)dA ) at the inlet and the outlet. Figure 9
