Water flows in the branching pipe shown in Fig. P4.36 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 = 20.2 s, (b) the fluid that left the control volume during that 0.2-s interval, and (c) the fluid that entered the control volume during that time interval.
