6. Water flows in the branching pipe shown in Fig. 2 with uniform velocity at each inlet and outlet. The fixed control volume indicated coincides with the system at time t = 20 s. Make a sketch to indicate (a) the boundary of the system at time t = 20.1 s, (b) the fluid that left the control volume during that 0.1-s interval, and (c) the fluid that entered the control volume during that time interval. V3 = 2.5 m/s (3) Control volume 0.8 m V = 2 m/s (1) 0.5 m (2) 0.6 m V = 1 m/s Figure 2
