Hydraulic test
Employing pressurized water to test a plumbing line for pressure integrity.
Hydrocarbons
Class of chemical compounds consisting of hydrogen and carbon.
Hydrochlorofluorocarbons (HCFCs)
Compounds comprised of hydrogen, chlorine, fluorine, and carbon atoms. They do not persist to the same extent as chloroflourocarbons, and so do not pose as great a threat to the ozone layer.
Hydrofluorocarbons (HFCs)
Compounds comprised of hydrogen, fluorine, and carbon atoms. Because they do not contain chlorine, they are not involved in ozone depletion.
Hydrostatic head
The pressure in a fluid, expressed as the height of a column of fluid, which will provide an equal pressure at the base of the column.
Hydrostatic pressure
Pressure exerted by water, or equivalent to that exerted on a surface by water in a column of specific height.
Hydrostatic strength
The capability of a pipe to resist internal pressure buildup, measured under specific conditions.
Hygrometer
An instrument used for measuring the moisture content of air.
Hygroscopic
Having the tendency to absorb and retain moisture from the air.
Hypotenuse
The side of a right triangle that faces the right angle.
