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

1. 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

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