Water (density 1000 kg/m³) flows upward from the basement to the first floor through a vertical pipe. At the basement level the pipe’s inner diameter is 4.0 cm and the gauge pressure there is 2.2×105Pa. Three metres higher, the pipe’s inner diameter is 2.0 cm and the flow speed is 2.0 m/s. Determine the gauge pressure at the first-floor location.
