The lowest temperature at which water may remain in liquid form is 33 degrees F.
Sea water pressure doubles every 33 feet of depth. The pressure increases at the rate of 1 atmosphere for every 10 m (33 ft) of depth. Ocean salinities commonly range between 33% to 38%, with an average of about 35%.
Since atmospheric pressure will support a column of water no higher than about 33 ft (10 m), a lift pump can raise water no farther than this distance.
Measurements for the Beaufort Scale (a system used to record wind speed) are made at 33 feet above ground level.
