Water at a gauge pressure of 3.8 atm at street level flows in to an office building at a speed of 0.06 m/s through a pipe 5.0 cm in diameter. the pipes taper down to 2.6cm in diameter by the top floor, 18 m above. calculate the flow in the pipes, the velocity in the tapered pipe, the absolute pressure, and the gauge pressure and in the pipe on the top floor. assume no branch pipe and ignore viscosity.
