Problem
A horizontal section of pipe gradually narrows to one-half its original cross-sectional area while also rising to a higher floor in a building. For water flowing steadily through the pipe and neglecting viscosity, which of the following describes the MOST likely changes in speed and gauge pressure of the water as it moves to the higher, narrower section?
(a) Speed decreases; gauge pressure increases
(b) Speed increases; gauge pressure decreases
(c) Speed decreases; gauge pressure decreases
(d) Speed increases; gauge pressure increases
