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

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 kPaposted by Scott

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