Control valves — are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a setpoint to a process variable whose value is… … Wikipedia
Flow measurement — is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive displacement flow meters acumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow… … Wikipedia
fluid mechanics — an applied science dealing with the basic principles of gaseous and liquid matter. Cf. fluid dynamics. [1940 45] * * * Study of the effects of forces and energy on liquids and gases. One branch of the field, hydrostatics, deals with fluids at… … Universalium
Flow chemistry — In flow chemistry, a chemical reaction is run in a continuously flowing stream rather than in batch production. In other words, pumps move fluid into a tube, and where tubes join one another, the fluids contact one another. If these fluids are… … Wikipedia
control system — Means by which a set of variable quantities is held constant or caused to vary in a prescribed way. Control systems are intimately related to the concept of automation but have an ancient history. Roman engineers maintained water levels in… … Universalium
Oil well control — is the management of the dangerous effects caused by unexpected high pressures upon surface equipment of oil or gas drilling rigs. Technically, oil well control involves preventing Formation fluid, usually referred to as kick, from entering into… … Wikipedia

Drilling fluid — This article is about fluids used when drilling a well. For fluids used with drill bits during metal working, see cutting fluid. Driller pouring a foaming agent down the rod string on a drilling rig In geotechnical engineering, drilling fluid is… … Wikipedia
Choked flow — is a compressible flow effect. The parameter that becomes choked or limited is the velocity or the mass flow rate. Choked flow is a fluid dynamic condition associated with the Venturi effect. When a flowing fluid at a given pressure and… … Wikipedia
Mass flow controller — A mass flow controller A mass flow controller (MFC) is a device used to measure and control the flow of fluids and gases. A mass flow controller is designed and calibrated to control a specific type of fluid or gas at a particular range of flow… … Wikipedia
Plug flow reactor model — The plug flow reactor (PFR) model is used to describe chemical reactions in continuous, flowing systems. The PFR model is used to predict the behaviour of chemical reactors, so that key reactor variables, such as the dimensions of the reactor,… … Wikipedia
