Hydrostatic Water Pressure
Water pressure increases in direct relation to its height, for example the higher the water is from the point of measured the higher the measured pressure.
Water in a tank 10 meters high will exert a pressure of 1 Bar. The table below shows the height of the water column in meters and feet and the pressure created measured in Pka, Bar, atmospheres (atm) and psi (pounds per square inch).
