Local Area Network

Networks with computers geographically close together (that is, in the same building).

Factor estimate for an entire facility derived solely from equipment costs.

A means of expressing the degree of saturation of water as related to calcium carbonate solubility.

A measure of the degree of saturation of calcium carbonate in water that is based on pH, alkalinity, and hardness. If the Langelier Index is negative, the water is corrosive (pH value below 7 or acidic). If the Langelier Index is positive, calcium carbonate can precipitate out of solution to form scale (pH value above 7 or basic). The Langelier Index will vary for cold water and for warm water.

Legally Authorized Representative

(also see: Biologics).

A classification of ICs [chips] based on their size as expressed by the number of circuits or logic gates they contain. An LSI IC contains 3,000 to 100,000 transistors.

Loading Accumulation Table

(ISO) The time interval between the instant at which a CPU's instruction control unit initiates a call for data and the instant at which the actual transfer of the data starts. Synonymous: Waiting Time.

The time between exposure and the first appearance of an effect.

The amount of heat needed to change a unit of substance, such as water, from a solid to a liquid without change in temperature or pressure.

Latent heat refers to the amount of energy released of absorbed by a chemical substance during a change of state, meaning a phase transition such as the melting of ice (latent heat of fusion) or the boiling of water (latent heat of vaporization). In an HVAC application typically used to condense water from humid air.

In metallurgy, the direction of the predominant surface pattern ordinarily determined by the production method used.

A vessel having a shell and/or heads made up of two or more separate layers.
