It is for this reason that any flow restriction causes an increase in the flowing velocity and also causes a drop in the static pressure of the flowing fluid. For noncompressible fluids, such as liquids, the equ ...

... Solution: • First, as always, we need to pick a control volume. In this case, we need two control volumes since there are two branches in the parallel pipe system. After careful thought (and experience), we decide that the most appropriate control volumes go between points (1) and (2) as labeled on ...
