The pressure exerted by a column of water when confined.
The force of the water available in a water supply system.
pressure which water exerts as measured in pounds per square inch, kilograms per square centimeter, head feet, or head meter.
The downward force of water upon itself and other materials; caused by the pull of gravity.
A term that refers to the pressure of water related to the limitations of a water softener. Too low pressures may require a separate pump to be installed.
force per unit area exerted by the weight of water, each 33 feet of sea water exerts a pressure equivalent to one atmosphere, or 14.7 psi.
The force of water that exists in a piping system; measured in pounds per square inch (PS).
The rate, measured in terms of pounds per square inch (psi), with which water flows into a house. Normal pressure is between 50 psi and 60 psi, and should not drop below 30 psi or rise higher than 80 psi.
