Water at a guage pressure of 3.8 atmospheres at sea level flows into Dansby building at a speed of 0.60 m.s trhough a pipe 5.0 cm in diameter. The pipe tapers down to 2.6cm in diamter by the top floor, 18.0m above where the faucet has been left open. Calculate the flow velocity and the gauge pressure in such a pipe on the top floor assuming no branch pipes and ignore viscosity.
