Water at a gauge pressure of PPP = 3.2 atmatm at street level flows into an office building at a speed of 0.64 m/sm/s through a pipe 5.2 cmcm in diameter. The pipe tapers down to 2.4 cmcm in diameter by the top floor, 16 mm above (Figure 1). Assume no branch pipes and ignore viscosity.

a) Calculate the flow velocity in the pipe on the top floor.

b) Calculate the gauge pressure in the pipe on the top floor.
