Composite partial pressure means the sum of the partial pressures of the VOC compounds in a solvent.
Operating pressure means the pressure at which the parts of an irrigation system are designed by the manufacturer to operate.
Backpressure means a pressure (caused by a pump, elevated tank or piping, boiler, or other means) on the consumer's side of the service connection that is greater than the pressure provided by the public water system and which may cause backflow.
Diameter means the diameter of the stem of a tree measured outside the bark at a specified point of measurement.
Sewage sludge weight means the weight of sewage sludge, in dry U.S. tons, including admixtures such as liming materials or bulking agents. Monitoring frequencies for sewage sludge parameters are based on the reported sludge weight generated in a calendar year (use the most recent calendar year data when the NPDES permit is up for renewal).
Design pressure means the hydrostatic pressure for which each structure or appliance assumed watertight in the intact and damage stability calculations is designed to withstand.
Process weight means the total weight of all materials introduced into any source operation. Solid fuels charged will be considered as part of the process weight, but liquid and gaseous fuels and combustion air will not.
Width means, in relation to a lot,
Floor coating means an opaque coating that is labeled and designed for application to flooring, including but not limited to, decks, porches, steps, and other horizontal surfaces which may be subject to foot traffic.
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
Lot width means the shorter of the following two linear measurements:
Pressure means the total load or force per unit area acting on a surface.
Antenna coating means a coating labeled and formulated exclusively for application to equipment and associated structural appurtenances that are used to receive or transmit electromagnetic signals.
Reid vapor pressure means the vapor pressure of crude oil or other volatile petroleum products at 100 degrees Fahrenheit as determined by the latest edition of ASTM D6377 (RVPE): Standard Test Method for Determination of Vapor Pressure of Crude Oil.
Acre-foot means the amount of water necessary to cover one acre of land one foot deep, or about 325,851 U. S. gallons of water.
Interconnector means equipment used to link the electricity system of the State to electricity systems outside of the State;
Nominal tomographic section thickness means the full width at half-maximum of the sensitivity profile taken at the center of the cross-sectional volume over which x-ray transmission data are collected.
Energy efficiency improvement means equipment, devices, or materials intended to decrease energy consumption, including, but not limited to, all of the following:
Runoff coefficient means the fraction of total rainfall that will appear at the conveyance as runoff.
Gasification means the substoichiometric oxidation or steam reformation of a substance to produce a gaseous mixture containing two or more of the following: (i) oxides of carbon; (ii) methane; and (iii) hydrogen;
Turbidity means the cloudy condition of water due to the presence of extremely fine particulate materials in suspension that interfere with the passage of light.
Wind Turbine means a mechanical/electrical system that converts the kinetic energy of blowing wind into mechanical or electric power.
Direct scattered radiation means that scattered radiation which has been deviated in direction only by materials irradiated by the useful beam (See "Scattered radiation").
PAD means a Preauthorized Debit.
Drainage area means a geographic area within which stormwater, sediments, or dissolved materials drain to a particular receiving waterbody or to a particular point along a receiving waterbody.
Basement means any area of the building having its floor subgrade (below ground level) on all sides.
Finished water means the water that is introduced into the distribution system of a public water system and is intended for distribution and consumption without further treatment, except as treatment necessary to maintain water quality in the distribution system (e.g., booster disinfection, addition of corrosion control chemicals).
