A student in the coast region (sea level) made a barometer using sea-water of density 1030kg/m^3. If the atmosphere pressure is 103000 N/m^2, what is the minimum length of the tube did the student use for the water column?

joseph
Pressure in liquid given by P=pgh
But P= atmosphere pressure
Therefore, pgh = atmosphere pressure
Hx1030x10 = 103000
H = 103000/10300
H= 10m

Next:  Describe an experiment to show that pressure in a liquid increases with depth.
Previous:  A sea diver is 45m below the surface of sea water. Given that the density of the sea water is 1030kg/m^3 and g=10kg/kg atmospheric pressure...
