Water is to be pumped to the top of a skyscraper, which is 1270 ft high. What gauge pressure is needed in the water line at the base of the building to raise the water to this height?

  • physics -

    1270 ft = 387 m,
    Pressure (Pa) = Density (1000 kg/m3) x Acceleration (9.8m/s2) x Height (m) =
    1000•9.8•387 =3.8•10^6 Pa
