Absolute Pressure in Fresh Water
Fresh water is less dense than salt water, so the rate of pressure increase is slightly different. Pressure increases by 1 atmosphere every 34 feet, as opposed to 33 feet for salt water.
As the graph to the left illustrates, the pressure at 34 feet of fresh water is 2 atmospheres, 3 atmospheres at 68 feet, and 4 atmospheres at 102 feet. The pressure continues to increase by 1 atmosphere every 34 feet.
