pressure units
1Pressure head — is a term used in fluid mechanics to represent the internal energy of a fluid due to the pressure exerted on its container. It may also be called static pressure head or simply static head (but not static head pressure). It is mathematically… …
2Pressure — This article is about pressure in the physical sciences. For other uses, see Pressure (disambiguation). Pressure as exerted by particle collisions inside a closed container …
3Pressure 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… …
4Pressure cooking — is a method of cooking in a sealed vessel that does not permit air or liquids to escape below a preset pressure. Because the boiling point of water increases as the pressure increases, the pressure built up inside the cooker allows the liquid in… …
5Pressure 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 …
6Pressure 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… …
7Pressure washer — A pressure washer is a mechanical device that uses high pressure water to remove mold, grime, dust, mud and dirt from surfaces and objects such as buildings, vehicles and concrete road surfaces. Equipment can be rented or bought that produces… …
8Units conversion by factor-label — Many, if not most, parameters and measurements in the physical sciences and engineering are expressed as a numerical quantity and a corresponding dimensional unit; for example: 1000 kg/m³, 100 kPa/bar, 50 miles per hour, 1000 Btu/lb. Converting… …
9Pressure sensor — Digital air pressure sensor Compact digital barometric pressure sensor A pressure sensor measure …
10pressure — pressureless, adj. /presh euhr/, n., v., pressured, pressuring. n. 1. the exertion of force upon a surface by an object, fluid, etc., in contact with it: the pressure of earth against a wall. 2. Physics. force per unit area. Symbol: P Cf. stress… …
