Water at a gauge pressure of P = 4.2 atm at street level flows into an office building at a speed of 0.76 m/s through a pipe 5.0 cm in diameter. The pipe tapers down to 3.0 cm in diameter by the top floor, 16 m above (Figure 1). Assume no branch pipes and ignore viscosity.
Part A
Calculate the flow velocity in the pipe on the top floor.
Express your answer to two significant figures and include the appropriate units.

Part B
Calculate the gauge pressure in the pipe on the top floor.
Express your answer to two significant figures and include the appropriate units.
