Figure P18.27 shows streamlines of water flowing in two regions (A) and (B) of the same pipe

Question:

Figure P18.27 shows streamlines of water flowing in two regions $A$ and $B$ of the same pipe (neither of the two regions shown spans the entire diameter of the pipe). Between these two regions no other pipes are connected to this one. Compare the speed, pressure, and pipe diameter in the two regions $\mathrm{A}$ and B .
