water at a gauge pressure of 3.8 atm at street level at a speed of 0.60 m/s through a pipe 5.0 in diameter the pipe tapers down to 2.

water at a gauge pressure of 3.8 atm at street level at a speed of 0.60 m/s through a pipe 5.0 in diameter the pipe tapers down to 2.6 cm in diameter by the top floor 18 above calculate the flow velocity and the gauge pressure in such a pipe on the top floor
