You drill a well to a depth of 100-m. Find the difference in water pressure, comparing the top and bottom of the well

  • Physics -

    the metric unit of pressure is the Pascal (Pa) ... one Newton of force over one square meter

    a cubic meter of water has a mass of a thousand kg (a metric ton)
    ... it exerts a force of 9.81 kN

    stacked 100 high, the pressure at the bottom is ... 981 kPa

  • Physics -

    take a 1 inch area pipe down.
    pressure=densitywater*height*9.8N/kg
