Water at a gauge pressure of PPP = 3.6 atmatm at street level flows into an office building at a speed of 0.96 m/sm/s through a pipe 5.6 cmcm in diameter. The pipe tapers down to 2.8 cmcm in diameter by the top floor, 16 mm above (Figure 1), where the faucet has been left open. Assume no branch pipes and ignore viscosity.
a.Calculate the flow velocity.
b.Calculate the gauge pressure in the pipe on the top floor.
