1Pressure swing adsorption — (PSA) is a technology used to separate some gas species from a mixture of gases under pressure according to the species molecular characteristics and affinity for an adsorbent material. It operates at near ambient temperatures and so differs from …
2Scale analysis (mathematics) — Scale analysis is a powerful tool used in the mathematical sciences for the simplification of equations with many terms. First the approximate magnitude of individual terms in the equations is determined. Then some negligibly small terms may be… …

4Pressure measurement — The construction of a bourdon tube gauge, construction elements are made of brass Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges. A… …
5Scale height — A scale height is a term often used in scientific contexts for a distance over which a quantity decreases by a factor of e. It is usually denoted by the capital letter H .For planetary atmospheres, it is the vertical distance upwards, over which… …
6Scale invariance — In physics and mathematics, scale invariance is a feature of objects or laws that do not change if length scales (or energy scales) are multiplied by a common factor. The technical term for this transformation is a dilatation (also known as… …
7Pressure vessel — Vertical pressure vessels installed in a structure A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. The pressure differential is dangerous and many fatal… …
8Pressure sensor — Digital air pressure sensor Compact digital barometric pressure sensor A pressure sensor measure …
9Pressure exchanger — A pressure exchanger transfers pressure energy from a high pressure fluid stream to a low pressure fluid stream. Many industrial processes operate at elevated pressures and have high pressure waste streams. One way of providing a high pressure… …
10pressure gauge — 1. an instrument for measuring the pressure of a gas or liquid. 2. an instrument used to determine the pressure in the bore or chamber of a gun when the charge explodes. [1860 65] * * * Instrument for measuring the condition of a fluid (liquid or …
