Water at a gauge pressure of P = 3.4 atm at
street level flows into an office building at a speed of
0.64 m/s through a pipe 5.4 cm in diameter. The
pipe tapers down to 2.8 cm in diameter by the top floor,
16 m above (Figure 1). Assume no branch pipes and
ignore viscosity.
Calculate the flow velocity in the pipe on the top floor.
Calculate the gauge pressure in the pipe on the top floor.
